Wed Apr 5 14:32:51 1995 Gary Houston <ghouston@actrix.gen.nz>
* unix.c, ioext.c, posix.c, sys.c: Scheme name changes,
semantic cleanups, the port table, missing system calls
and coding cleanups from ghouston@actrix.gen.nz
Thu Mar 16 14:37:38 1995 Tom Lord <lord@x1.cygnus.com>
* guile.c: fixed the gcc-specific definition of the macro "AT(x)".
* guile.c (gscm_init_from_fn): Parameterize what init functions
get called (see guile_ks, below).
* guile-mini.c (guile_mini): a minimalist alternative to guile_ks.
* guile-ks.c (guile_ks): factor out the call to optional inits to
a separate file so you can link against libguile without getting
the kitchen sink.
* Ginit.scm (try-load of "ScmInit.scm"): Be robust in the absense
of a binding for the environment varialbe HOME. Try
(getpw (geteuid)) or just use "/".
Thu Mar 9 15:35:20 1995 Tom Lord <lord@x1.cygnus.com>
* gmain.c (main): Print additional error message if init file
can't be opened.
* guile.c (initialize_gscm): Report an error if the
init file can't be opened.
Thu Mar 23 23:22:59 1995 Aubrey Jaffer (jaffer@jacal)
* scm.texi (I/O-Extensions): Finished.
* Init.scm (scm:load): `loading' messages now indented.
Sat Mar 4 20:58:51 1995 Aubrey Jaffer (jaffer@jacal)
* scm.texi: documentation finished for "posix.c" and "unix.c".
* posix.c (scm_getgroups): added.
* posix.c (makfrom0str): According to glibc.info, some field in
structures like pwent may have NULL pointers. Changed makfrom0str
to return BOOL_F in this case.
Thu Mar 2 12:52:25 1995 Aubrey Jaffer (jaffer@jacal)
* time.c: CLKTCK set from CLOCKS_PER_SEC, if available. Metaware
HighC ported.
* scm.h: USE_ANSI_PROTOTYPES now controls prototypes (was
__STDC__). This allows an overly fussy compiler to still have
__STDC__.
From: dorai@ses.com (Dorai Sitaram)
* ioext.c (l_utime): include files fixed for __EMX__
Sun Feb 26 23:46:18 1995 Tom Lord <lord@x1.cygnus.com>
* repl.c (scm_app_wdr): Like scm_apply, but takes an error function.
The caller's continuation is never captured or escaped.
The error function is invoked as with scm_cwdr.
Sun Feb 26 21:03:04 1995 Aubrey Jaffer (jaffer@jacal)
* sys.c (gc_mark gc_sweep): tc7_ssymbol now gets GCed because it
gets used for non-GCed strings in scm_evalstr scm_loadstr.
(mkstrport cwos cwis): changed so caller's name is passed into
mkstrport().
* repl.c
(scm_eval_string scm_evalstr scm_load_string scm_loadstr): added
for easier C to scheme callbacks.
(loadport): variable added so lreadr() and flush_ws()
increment linum only when reading from the correct port.
(def_err_response): now handles ARGn for argument numbers > 5 and
unknown position arguments.
* dynl.c: Dynamic Linking now sets and restores *load-pathname*
around the init_ call.
Sat Feb 25 11:03:56 1995 Aubrey Jaffer (jaffer@jacal)
* scm.c (lsystem getenv softtype ed vms_debug): moved from scl.c.
(add_feature): moved from repl.c.
(features): init table removed (caused multiple symbols).
Fri Feb 24 23:48:03 1995 Aubrey Jaffer (jaffer@jacal)
* scm.c (scm_init_extensions COMPILED_INITS): Added so that
statically linked, compiled code can be initialized *after* most
of Init.scm has loaded.
Wed Feb 22 15:54:01 1995 Aubrey Jaffer (jaffer@jacal)
* subr.c (append): Added check for bad arguments and fixed errobj.
Sun Feb 19 01:31:59 1995 Aubrey Jaffer (jaffer@jacal)
* ioext.c (exec execp): changed so that 2nd arguments is argv[0]
(like posix) and renamed to execl and execlp.
(execv execvp): added.
Sat Feb 11 17:30:14 1995 Aubrey Jaffer (jaffer@jacal)
* ioext.c (lexec): moved from repl.c and scm.c.
(lexecp i_exec l_putenv): added.
* posix.c (open_pipe l_open_input_pipe l_open_output_pipe
prinpipe): moved from ioext.c.
(l_fork): added.
Fri Feb 10 10:50:03 1995 Aubrey Jaffer (jaffer@jacal)
* scl.c (num2long long2num): moved here from subr.c.
(num2ulong): fixed (< to >=) bug.
* unif.c (aset array2list array_ref cvref): uniform integers and
unsigned integer arrays now handle full size integers (and
inexacts) using num2long, num2ulong, long2num, and ulong2num when
INUMS_ONLY is not defined.
* scmfig.h (INUMS_ONLY): defined when INUMs are the only numbers.
Wed Feb 8 17:57:26 1995 Tom Lord (lord@x1.cygnus.com)
* Ginit.scm (stand-alone-repl): Use new function (rooted-repl)
(rooted-repl): new function
Tue Jan 31 16:46:26 1995 Tom Lord (lord@x1.cygnus.com)
* repl.c (lreadr): compare string constant names
in a case insensative way.
(scm_lread): Take an optional parameter CASEP.
If specified and not #f, then symbols are read
in a case sensative way.
If not specified, the state variable default_case_i is checked
(a C int, either 0 or 1). The state variable hasn't been
exposed and so is constant and depends on compile-time flags --
but in the future it might be made more explicit if there is a
need.
Sun Jan 29 23:22:40 1995 Aubrey Jaffer (jaffer@jacal)
* scm.texi (Overview): scm.1 converted to texinfo format and
incorporated.
Sat Jan 28 23:11:40 1995 Tom Lord (lord@x1.cygnus.com)
* repl.c (compiled-library-path): return the value of the
compile-time cpp macro "LIBRARY_PATH" or #f.
* Ginit.scm: use the above path to find slib on unix.
This solution should be generalized.
Fri Jan 27 19:58:27 1995 Tom Lord (lord@x1.cygnus.com)
* sys.c (gc_sweep): Fixed a gc bug that caused circular free-lists
resulting in Cells that thought they were free long after they
were allocated for some nefarious purpose or other.
* Makefile.in (manifest): ship all pieces of the info manual.
Typos fixes from ghouston.
Thu Jan 26 01:52:00 1995 Tom Lord <lord@x1.cygnus.com>
From: cessu@cs.hut.fi (Kenneth Oksanen)
* configure.in:
AC_CHECK_LIB(nsl, gethostent)
AC_CHECK_LIB(ucb, bzero)
AC_CHECK_LIB(socket, socket)
AC_CHECK_LIB(bsd, bzero)
From: brent@jade.ssd.csd.harris.com (Brent Benson)
* gmain.c: line 31: In ANSI C, string literals cannot span multiple
source lines.
* guile.c: line 592: The two cases in the ifdef are reversed, AT(X)
should expand to nothing if you are *not* using GNUC.
* ioext.c: line 29: On my system it is necessary to
include <unistd.h> *before* <sys/stat.h> in order to
have the correct types defined.
* ioext.c: line 194: Declaration of popen conflicts with my system's
popen() defined in <unistd.h>. Let the header file provide the
prototype!!
Sun Jan 22 11:13:58 1995 Aubrey Jaffer (jaffer@jacal)
* scm.texi (Internals): code.doc converted to texinfo format.
Much added and reorganized. code.doc removed.
Thu Jan 19 00:40:11 1995 Aubrey Jaffer (jaffer@jacal)
* subr.c (logbitp logtest): added.
Mon Jan 16 01:42:20 1995 Tom Lord <lord@x1.cygnus.com>
* repl.c (scm_repl): takes two arguments now (prompt and top-level).
Callable from Scheme.
* sys.c (scm_init_storage): only use stdin if scm_take_stdin is true.
Otherwise, use an empty string port. If using stdin, make it
unbuffered.
Sun Jan 15 21:51:37 1995 Tom Lord <lord@x1.cygnus.com>
* sys.c (scm_mkarray, scm_free_array, mark_arrays): support for
C programs. malloc/free style interface to allcoating
protected storage of type SCM*.
Sun Jan 15 17:49:43 1995 Tom Lord (lord@x1.cygnus.com)
* guile.c: new file. Friendly C interface for Guile.
(see file GUILE)
* repl.c (scm_cwdr): added call-with-dynamic-root (see scm.texi).
Sat Jan 14 23:35:21 1995 Tom Lord (lord@x1.cygnus.com)
* repl.c, subr.c: re-arrangement, commenting
of source in preparation for pulling repls apart
for libguile.
Wed Jan 11 14:45:17 1995 Aubrey Jaffer (jaffer@jacal)
* scl.c (num2ulong): checks for bignum sign and magnitude added.
* subr.c (logand logior logxor lognot): lognot restriction to
INUMs removed. Logand, logior, and logxor now will work for up to
32 bit signed numbers.
Tue Jan 10 13:19:52 1995 Aubrey Jaffer (jaffer@jacal)
* repl.c (def_err_response): Circuitous call to quit() replaced
with exit(EXIT_FAILURE);
(everr): Now calls def_err_response() in interrupt frame if
errjmp_bad or there are dynwinds to do. This prevents silent
failure in batch mode.
Mon Jan 9 00:12:14 1995 Aubrey Jaffer (jaffer@jacal)
* repl.c (handle_it): Now discards possibly used top freelist cell
for GC safety. Also now just punts if errjmp_bad.
* scm.texi: converted from MANUAL. GUILE documentation merged in.
Sat Jan 7 13:51:04 1995 Miles Bader (miles@eskimo.com)
* mrequire.scm: New file: Wrapper for slib require/provide that
makes it modular (that is, each slib package is loaded into its
own module, and sees only other modules that it requires).
* defmod.scm: Allow use-interface in the default module.
* libguile.scm: Put symbols common to both guile and scm
interfaces into the internal interface `EXTRA' (which is included
by both). Other random shuffling, mostly to make slib happy.
* modops.scm (extend-interface, export-interface, export): Add
another operation type, #f, which turns off automatic exporting of
the current source interface when finishing up with it. This is
used by export-interface to prevent trying to export all symbols.
* modops.scm (import): No longer signal an error when trying to
export a whole module, as we want to do this sometimes.
* Ginit.scm: No longer try to load require.scm, or depend on it;
In the case of getopt, we just load it manually. Also make
defmacro module-safe.
Sat Jan 7 01:54:11 1995 Tom Lord <lord@x1.cygnus.com>
* sys.c (scm_intern_obarray_soft): Reserve room for symbol slots.
* sys.c (scm_makstr, scm_makfromstr): added an extra parameter SLOTS.
The parameter means:
0: same as the old behavior
1: not useful
> 1: allocate SLOTS - 1 extra slots in the string storage.
The base address of SLOTS, an array of SCM, is at SLOTS(obj).
This is for symbol slots, and later for procedure slots.
If you use this in the constructor for your new type (usually
done by creating a string and then invoking SETLENGTH to change
its type), you are responsible for making sure slot contents
are properly gc'ed.
Callers of these were fixed as well.
Tue Jan 3 14:30:34 1995 Miles Bader (miles@eskimo.com)
* modops.scm, extlibs.scm, libguile.scm, defmod.scm: New files:
These implement the user-level module system.
* sys.c (scm_sym2vcell): Add another argument: definedp, which is
passed as additional argument to the lookup-thunk (if any).
If this argument is BOOL_T, this lookup is for a define (which
has somewhat different semantics for modules); otherwise it
should be satisfied with an existing variable. If the thunk
returns BOOL_F (meaning there was no such variable), sym2vcell
returns BOOL_F as well.
* eval.c (scm_lookupcar, scm_m_define): Use the new sym2vcell param.
* variable.c (scm_builtin_var): Use the new sym2vcell param.
* eval.c (scm_top_level_env): New function: return an environment
using the given top-level-lookup thunk.
* eval.c (scm_eval2): Use scm_top_level_env.
* eval.c (scm_eval): Use an env with a top-level lookup thunk from
scm_top_level_lookup_thunk_var (aka *top-level-lookup-thunk*).
* eval.c (scm_neval): New function: just like scm_eval, but may
destroy its argument. Known in scheme as eval!.
* repl.c (scm_repl, scm_tryload, lreadr): Use scm_neval, not eval_3.
* Ginit.scm (make-module): Use the new definition of top-level thunks.
* Ginit.scm (set-current-module): Set *top-level-lookup-thunk* too.
* Ginit.scm: Trash all the repl stuff; we just use the C repl now.
Load the user module system.
* Makefile.in: Install the user-module implementation files.
Mon Jan 2 16:27:25 1995 Miles Bader (miles@eskimo.com)
* Ginit.scm (repl:repl): Have the guile repl redefine try-load
instead of load, as this is the SCM primitive.
(module-for-each): Write module-for-each.
(module-search): Make this recurse into each module use-list
entry, as per the low-level module spec.
(define-macro): Make this function usable by modules that don't
have access to the internals of the guile module.
Sun Jan 1 22:30:25 1995 Tom Lord <lord@x1.cygnus.com>
* repl.c (scm_iprin1), subr.c (scm_lock_vector, scm_unlock_vector,
scm_lvector_ref, scm_lvector_set):
Added locked vectors. See N
Sat Dec 31 15:45:22 1994 Miles Bader <miles@eskimo.com>
* Ginit.scm:
Add define-macro, delq!.
Add a module print-function, and some new name fields
to the module that the modops code uses to make modules
print nicely (e.g., #<interface guile/module 7a89c>)
* eval.c(ceval): Here's a patch that makes closures & subrs
self-evaluating.
Wed Dec 28 00:31:22 1994 Tom Lord <lord@cygnus.com>
* scm.c (raise): use kill not raise, since it is more portable.
Wed Dec 21 05:18:47 1994 Tom Lord <lord@x1.cygnus.com>
* eval.c (scm_eval2): Two argument eval. The
second argument is #f or a proc returning a variable.
Fri Dec 9 00:40:26 1994 Tom Lord <lord@x1.cygnus.com>
* eval.c (scm_fasl_eval): eval without copying the source form.
This is just a temporary hack.
Sun Dec 4 21:50:37 1994 Tom Lord <lord@x1.cygnus.com>
* eval.c (scm_ceval): Added special forms LITERAL-VARIABLE-SET!
and LITERAL-VARIABLE-REF. The first argument of each is a
variable object (see variable.c). The second argument
of set! is an expression. They do what you'd expect.
-SET! returns UNSPECIFIED.
Note that one can not read a form which uses literal-variable*
correctly because there is no way to read a variable object.
These forms exist for the sake of the module system.
Fri Dec 2 19:52:40 1994 Tom Lord (lord@x1.cygnus.com)
* subr.c (string->obarray-symbol, intern-symbol, unintern-symbol,
symbol-set!, symbol-binding)
Multiple obarrays.
* variable.c (scm_make_variable, scm_variable_{ref,set}
Implemented variables. Variables are anonymous
objects holding one settable value.
Wed Nov 30 04:31:18 1994 Tom Lord (lord@x1.cygnus.com)
* *.[ch]: renamed all global identifiers to have the prefix scm_.
* sys.c (gc_sweep, scm_mark_locations, scm_init_heap):
Modified gc to allow objects of any multiple of sizeof(CELLPTR).
In addition, each heap segment gets to specify a freelist (which
may be shared).
new function: scm_alloc_obj
new vars: scm_heap_table (replaces hplims)
scm_n_heap_segs (replaces (hpims_ind / 2))
Thu Oct 27 12:57:02 1994 Aubrey Jaffer (jaffer@jacal)
From: Jerry D. Hedden <hedden@esdsdf.dnet.ge.com>
* ioext.c: conditional code for vms and version (3.6) of Aztec C.
* pi.scm ((e digits)): Modified 'bigpi' for slight speed
improvement. Added function to calculate digits of 'e'.
Wed Oct 26 11:22:05 1994 Aubrey Jaffer (jaffer@jacal)
From: Gary Houston <ghouston@actrix.gen.nz>
* scl.c (round): Now rounds as described in R4RS.
* test.scm (test-inexact): test cases for round.
Tue Oct 25 00:02:27 1994 Aubrey Jaffer (jaffer@jacal)
* sys.c (grow_throw lthrow dynthrow): now pass arrays, check
for adequate growth, and clear out register windows (on sparc).
Mon Oct 24 01:05:34 1994 Aubrey Jaffer (jaffer@jacal)
* ioext.c (ttyname fileno): added.
Sat Oct 22 12:12:57 1994 Aubrey Jaffer (jaffer@jacal)
* unix.c (symlink readlink lstat): added.
* scmfig.h repl.c sys.c (IO_EXTENSIONS): flag removed.
* ioext.c (read-line read-line! file-position, file-set-position
reopen-file open-pipe opendir readdir rewinddir closedir chdir
umask rename-file isatty? access chmod mkdir rmdir stat utime
raise): moved from "repl.c" and "sys.c".
Fri Oct 21 21:19:13 1994 Aubrey Jaffer (jaffer@jacal)
From: Radey Shouman <shouman@ccwf.cc.utexas.edu>
* unif.c (ra2contig): now has a second parameter to indicate
whether copying is necessary or not. Eliminates gratuitous copy
by UNIFORM-ARRAY-READ! when called with a noncontiguous array.
(array_map): more liberal check on when ARRAY-MAP! can use
array-ified asubrs.
Thu Oct 20 18:00:35 1994 Aubrey Jaffer (jaffer@jacal)
* sys.c (opendir readdir rewinddir closedir reopen-file): added
under IO_EXTENSIONS.
Wed Oct 19 14:18:26 1994 Aubrey Jaffer (jaffer@jacal)
* eval.c (badargsp): added under ifndef RECKLESS to check @apply
and apply() arg counts.
Tue Oct 18 00:02:10 1994 Aubrey Jaffer (jaffer@jacal)
* unix.c (mknod acct nice sync): added.
* socket.c (socket bind! gethost connect! listen! accept): added.
* time.c (utime): added under IO_EXTENSIONS.
Mon Oct 17 23:49:06 1994 Aubrey Jaffer (jaffer@jacal)
* sys.c (getcwd umask access chmod mkdir rmdir): added
under IO_EXTENSIONS.
* scm.c (l_pause): added if SIGALRM defined.
(l_sleep): added if SIGALRM not defined.

Sun Oct 16 22:41:04 1994 Aubrey Jaffer (jaffer@jacal)
* sys.c (access chmod): Posix access added under IO_EXTENSIONS.
Fri Oct 14 09:45:32 1994 Aubrey Jaffer (jaffer@jacal)
* posix.c (chown link pipe waitpid, kill, getpw, getgr, get*id,
set*id): added.
* time.c (l_raise l_getpid): added
* subr.c (ulong2big):
* scl.c (ulong2num): useful routines for system call data
conversion moved from "time.c".
Thu Sep 22 14:48:16 1994 Aubrey Jaffer (jaffer@jacal)
* subr.c (big2inum): (more accruately) renamed from big2long.
Tue Sep 6 22:22:16 1994 Aubrey Jaffer (jaffer@jacal)
From: rshouman@hpcf.cc.utexas.edu (Radey Shouman)
Date: Mon, 29 Aug 1994 11:36:46 +0600
* unif.c: This is a large patch, but also a bit larger than it
appears -- I moved a few function definitions around to eliminate
gratuitous forward references.
* unif.c repl.c (raprin1): Combined print routine for arrays with
that for uves.
* unif.c (UNIFORM-VECTOR-READ! and -WRITE): work with general
arrays, by copying when necessary, renamed them to
UNIFORM-ARRAY-READ! and -WRITE.
* unif.c (ARRAY-CONTENTS): Generalized so that it returns a 1-d
array even when the stride in the last dimension is greater than
one, gave it an optional second argument STRICT, which makes it
behave as it did before, returning an array/vector only if the
contents are contiguous in memory.
* unif.c (ARRAY-CONTIGUOUS?) Eliminated. Instead, use
(lambda (ra) (array? (array-contents ra #t)))
* unif.c code.doc (ramapc): unrolls arrays mapping into one loop
if possible, to make this quick, changed the format of the array
CAR, now uses one bit to indicate that an array is contiguous --
this still allows a ridiculous number of dimensions.
* scm.h (DSUBRF): dsubrs are mapped directly, to allow this I
moved the typedef for dsubr and #define for DSUBRF to scm.h
* unif.c (ARRAY-MAP!) taught something about subrs, now most subrs
may be mapped without going through apply(), saving time and
reducing consing. +, -, *, /, =, <, <=, >, and >= are mapped
directly as special cases -- for uniform arrays this is nearly as
fast as the equivalent C, and doesnt' cons. I've made sure that
+, -, *, and / vectorize on the CRAY, this may be wasted effort
but the effort is not great.
* unif.c (ARRAY-COPY!) now copies many arrays of differing types
to each other without going through the aref/aset, e.g. float ->
double, double -> complex, integer -> float ... This should make
array type coercions for arithmetic faster.
* unif.c (TRANSPOSE-ARRAY) Added, which returns a shared array
that is the transpose of its first argument. I think this does
what an APL:TRANSPOSE would.
* unif.c (ENCLOSE-ARRAY) Added, this returns an array that looks
like an array of shared arrays, the difference being that the
shared arrays are not actually allocated until referenced.
Internally, the contents of an enclosed array is another array.
The main reason for this is to allow a reasonably efficient
implementation of APL:COMPRESS, EXPAND, and INDEXING. In order to
actually make an array of shared arrays, just use ARRAY-COPY!.
* unif.c (cvref): Created internal version of aref(), cvref() that
doesn't do error checking; Thus speeding things up. Profiling of
SCM running array code revealed that aref() was taking a
surprising fraction of the CPU time
TO DO:
The mechanism for looking up the vectorized functions is a little
kludgy, I was tempted to steal some of the CAR of the subr type to
encode an offset into a table of vectorized functions, but this
would make it more likely that dynamically loaded subrs lose thier
names.
It is almost possible to write APL:+ and friends now, it is just
necessary to figure out the appropriate type of the returned array
and allocate it, and to promote scalar arguments to arrays (with
increments 0).
This doesn't include vectorized REAL-PART, IMAG-PART,
MAKE-RECTANGULAR ...
I think some C support for APL:REDUCE and maybe INNER-PRODUCT will
be needed for a reasonably fast APL.scm
unif.c is getting quite big, time to split it up?
Mon Sep 5 22:44:50 1994 Aubrey Jaffer (jaffer@jacal)
* Init.scm repl.c (quit): code was not using return values
correctly.
Sun Aug 21 01:02:48 1994 Aubrey Jaffer (jaffer@jacal)
* record.c (init_record): remaining record functions moved into C
code.
* eval.c sys.c: compiled closures now conditional under CCLO.
Sat Aug 20 23:03:36 1994 Aubrey Jaffer (jaffer@jacal)
From: rshouman@chpc.utexas.edu (Radey Shouman)
* eval.c (ceval apply):
* sys.c (makcclo): tc7_cclo, compiled closures, now supported.
* record.c (init_record): C implementation of slib "Record"s using
CCLO.
* scm.h subr.c (QUOTIENT MODULO REMAINDER): fixes a bug for
bignums with DIGSTOOBIG defined. Also, changed the return type of
longdigs() to void, since that value is no longer used anywhere.
Mon Aug 1 11:16:56 1994 Aubrey Jaffer (jaffer@jacal)
* time.c (curtime): replaces get-universal-time. Other time
functions removed (SLIB support more complete).
* subr.c (divbigbig): fixed (modulo -2177452800 86400) => 86400
bug. Also added to test.scm.
Sun Jul 24 16:09:48 1994 Aubrey Jaffer (jaffer@jacal)
* dynl.c (init_dynl): *feature* dld:dyncm added for dynamically
(ldso) linked libc.sa and libm.sa (under Linux).
Fri Jul 15 12:53:48 1994 Aubrey Jaffer (jaffer@jacal)
* unif.c (array-fill!): bug with increment in default clause fixed.
Fast string support added.
From: rshouman@chpc.utexas.edu (Radey Shouman)
* unif.c (array-fill! array-for-each): bug fixes.
Sun Jul 10 01:51:00 1994 Aubrey Jaffer (jaffer@jacal)

From: rshouman@chpc.utexas.edu (Radey Shouman)
* unif.c: no longer uses pointer comparisons in loops. Should
fix problems on 8086 processors.
* unif.c (make_sh_array): Fixes MAKE-SHARED-ARRAY so that shared
arrays with only 1 element in some direction may still be
ARRAY-CONTIGUOUS?
(uve_write uve_read): Fixes bug in UNIFORM-ARRAY-WRITE,
UNIFORM-ARRAY_READ!. Now they do the right thing for shared
bit-arrays not starting at the beginning of their contents vector.
(array_contents ARRAY-SIMPLE?): ARRAY-CONTENTS may now return a
shared, contiguous, 1-d array, instead of a vector, if the array
cannot access all of the contents vector. ARRAY-SIMPLE? removed.
(array-fill!): a replacement and generalization of
UNIFORM-VECTOR-FILL!.
(raequal): Combines with uve_equal(), providing also ARRAY-EQUAL?
ARRAY-EQUAL? is equivalent to EQUAL? if all its arguments are
uniform vectors or if all are arrays. It differs from EQUAL? in
that a shared, 1-d array may be ARRAY-EQUAL? to a uniform vector.
for example
(define sh (make-shared-array '#(0 1 2 3) list '(0 1))) ==> #1(0 1)
(equal? '#(0 1) sh) ==> #F
(array-equal? '#(0 1) sh) ==> #T
(list2ura): Combines list2uve() and list2ura().

(K&R C does not allow initialization of "automatic" arrays or
structures). This was not use in 4d2 or previously, and the
following patch ensures that such initialization only occurs for
ANSI C compilers (Note that K&R C compilers need to explicitly
assign the values).

time.
Mon Nov 1 18:47:04 1993 (jaffer at jacal)
* unif.c (uniform-vector-ref => array-ref): integrated arrays

* patchlvl.h (PATCHLEVEL): 4
* sys.c (gc_sweep): usaage of pclose() now conditional on unix.
* MANUAL (chdir): documented.
from T. Kurt Bond, Adminisoft, Inc. <tkb@MTNET2.WVNET.EDU>:
* repl.c sys.c (errno): VMS GNU C uses a special hack in <errno.h>
to get the link-time attributes for the errno variable to match
those the VMS C run-time library expects (it makes errno a
preprocessor define so that the variable that the compiler sees
has a special form that the assember then interprets), so if it is
VMS and __GNUC__ is defined <errno.h> needs included.
* setjump.h (SETJUMP LONGJUMP): SETJUMP and LONGJUMP changed to
setjump and longjump. The VMS linker is case-indifferent. VMS GNU
C mangles variable names that have upper case letters in them to
preserve their uniqueness.
* sys.c (iprint iprin1): Now inline putc loops instead of calls to
fwrite for VMS. The VMS `fwrite' has been enhanced to work with
VMS's Record Management Sevice, RMS. Part of this enhancement is
to treat each call to `fwrite' as producing a separate record.
This works fine if you are writing to a stream_LF file or an
actual terminal screen, but if you are writing to a file that has
implied carriage control (such as a batch log file, or a mailbox
used for subprocess communication), which is a more common file
organization for RMS, each call to `fwrite' has a newline appended
to it. This causes much of the output to be incorrectly split
across lines.
* vmsgcc.com: created.
