* dynl.c (scm_dynamic_func): Cast return value from sysdep_dynl_func.
* extchrs.c (xmbtowc): Make the second arg a normal char, not
unsigned, because that's what the ANSI function takes.
* extchrs.h (xmbtowc): Corresponding change to prototype.
* genio.c (scm_gen_getc): Make buf plain chars. Nobody wants
uchars here.
* mbstrings.c (scm_mb_ilength): Use ANSI arg syntax. Make DATA
argument plain char *.
* strings.c (scm_string): Use SCM_ROCHARS, since c is a plain
char.
* tag.c (scm_tag): Remove unreachable statement.
* unif.c (scm_array_to_list): If we want to shift a 1 bit to the
top of the word, it should be unsigned.
unif.c.
strop.h: move prototypes too.
* posix.c (scm_init_posix): don't intern EINTR since it's now done
elsewhere.
* ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
etc. I deleted them from filesys.c long ago, but didn't
notice they were here too (although ineffective since
sys/stat.h wasn't included).
* Makefile.am: remove AWK=@AWK@.
Add a rule for generating errnos.list.
(CLEANFILES): put errnos.list here instead of in DISTCLEANFILES.
* configure.in: add AC_SUBST(AWK) and AC_SUBST(ERRNO_EXTRACT).
don't extract errnos, just set a variable (avoids the
need to recompile error.c just because configure is run.)
* unif.h: update prototypes.
* unif.c (scm_uniform_array_read,write): change the offset and
length arguments to start and end, for consistency.
* __scm.h: uncomment SCM_ARG6 and SCM_ARG7, I needed SCM_ARG6.
* ioext.h: update prototypes.
* * ioext.c (scm_read_delimited_x): replaces scm_read_line and
scm_read_line_x, it's a more general procedure using an
interface from scsh. read-line and read-line! are now defined
in boot-9.scm.
* Note that the new read-line trims the terminator
by default, previously it was appended to the returned string. An
optional argument specifies how to process the terminator (scsh
compatible). For the old behaviour: (read-line port 'concat).
scm_read_line, scm_read_line_x: deleted. (read-line port 'split)
returns a pair, but is converted to multiple values if the scsh
module is loaded.
socket.h: update prototypes.
* socket.c (scm_recvfrom): for consistency with other procedures,
take start and end as separate optional arguments.
* (scm_recv, scm_recvfrom): don't allow the second argument
to be a size, only a buffer. Change the scheme names to
recv! and recvfrom!. Don't return the buffer.
* ioext.h, posix.h: move prototypes too.
* ioext.c, posix.c (scm_read_line, scm_read_line_x, scm_write_line:
moved back from posix.c to ioext.c. Also move #includes of "genio.h"
"read.h" and "unif.h".
* ioext.c: include "chars.h"
primitives.
load errno.scm.
* netconst.scm: undefine maybe-define and maybe-define-so after use.
* errno.scm: new file.
* fports.c (scm_open_file): pass errno to scm_syserror_msg.
* filesys.h: update prototypes. Remove macros: SCM_FD_P, SCM_FD_FLAGS,
SCM_FD.
* filesys.c (scm_sys_stat, scm_sys_lstat): pass errno to
scm_syserror_msg.
* (scm_sys_read_fd, scm_sys_write_fd, scm_sys_close, scm_sys_lseek,
scm_sys_dup): deleted: FD capability will be added to other
procedures.
* Remove support for the FD object type: scm_tc16_fd, scm_fd_print,
scm_fd_free, fd_smob, scm_intern_fd.
* (scm_open): renamed from scm_sys_open. Return a port instead of
an FD object. Make the mode argument optional.
* (scm_sys_create): deleted, it's just a special case of open.
(scm_init_filesys): move interning of constants O_CREAT etc.,
here (were previously using SCM_CONST_LONG macro).
Add missing constants: O_RDONLY, O_WRONLY, O_RDWR, O_CREAT.
don't newsmob fd.
(numerous _sys_ procedures): remove gratuitous _sys_ from names.
include "fports.h" and <stdio.h>
(scm_stat, scm_select): don't support FD objects.
* error.h: adjust scm_syserror_msg prototype.
* error.c (scm_syserror_msg): take an extra argument for errno.
Using the global value didn't always work, since it could be
reset by procedure calls in the message or args arguments.
* fports.c (scm_setbuf0): call setbuf even if FIONREAD is not defined.
I don't understand why the check was there (and what about the
ultrix check?)
* strop.c (scm_string_copy): allow shared substrings to be copied.
* unif.h: corresponding change to prototypes.
* unif.c (scm_uniform_array_read_x, scm_uniform_array_write_x):
recognize two new optional arguments: offset and length. Allow
the port argument to be an integer (file descriptor, for scsh).
Include <unistd.h> for "read" prototype.
ANSI declarations combined with K&R definitions. We'll
appease it a little bit. But when it invades France, we fight.
* print.c (scm_iprlist): Change 'tlr' argument to an int.
* print.h (scm_iprlist): Here too.
* numbers.c (scm_divbigdig): Change definition to match
declaration in numbers.h.
* unif.c (scm_makflo): Change definition to match declaration in
unif.h.
variables aren't used uninitialized.
* error.h (scm_error, scm_syserror, scm_syserror_msg,
scm_sysmissing, scm_num_overflow, scm_out_of_range,
scm_wrong_num_args, scm_wrong_type_arg, scm_memory_error,
scm_misc_error): Tell GCC that these functions never return.
* struct.c (scm_struct_ref, scm_struct_set_x): If we can't figure
out the field type, call abort if SCM_ASSERT returns, to placate
the optimizer.
* stacks.c (scm_make_stack, scm_last_stack_frame): abort if
scm_wta ever returns. We can't handle this case anyway, and this
gives the optimizer more information.
* unif.c (scm_uniform_vector_ref, scm_array_set_x): Abort if
scm_wta ever returns.
In some cases, the code is fine, but GCC isn't smart enough to
figure that out; this usually happens when one variable is only
initialized and used when a particular condition holds true, and
we know that condition will never change within a given invocation
of the function. In this case, we simply initialize the variables
to placate the compiler, hopefully to a value which will cause a
crash if it is ever actually used.
* print.c (scm_iprin1): Initialize mw_pos.
* read.c (scm_lreadrecparen): Initialize tl2, ans2.
* throw.c (scm_ithrow): Initialize dynpair.
* unif.c (scm_uniform_vector_ref): Initialize cra.
* struct.c (init_struct): Initialize prot.
* mbstrings.c (scm_print_mb_symbol): Initialize mw_pos and inc.
srcprop.h, tags.h, throw.c, unif.c: Added new selectors
SCM_SETAND_CAR, SCM_SETAND_CDR, SCM_SETOR_CAR and SCM_SETOR_CDR.
Motivation: Safer use. Some other macros are defined in terms of
these operations. If these are defined using the SCM_SETCXR
(<e1>, SCM_CXR (<e1>) <op> <e2>) pattern a complex <e1> will lead
to inefficiency and an <e1> with side-effects could potentially
break. Also, these particular operations are heavily utilized in
the garbage collector. In unoptimized code there will be a
measurable speedup.
* alist.c, arbiters.c, continuations.c, debug.c, debug.h, eval.c,
eval.h, feature.c, filesys.c, fports.c, gc.c, gsubr.c, init.c,
ioext.c, kw.c, list.c, load.c, mallocs.c, numbers.c, numbers.h,

procs.h, ramap.c, read.c, root.c, srcprop.c, srcprop.h,
strports.c, symbols.c, tags.h, throw.c, unif.c, variable.c,
vports.c: Cleaned up use of pairs: Don't make any special
assumptions about the internal structure of selectors and
mutators: SCM_CXR (<e1>) = <e2> --> SCM_SETCXR (<e1>, <e2>),
SCM_CXR (<e1>) &= <e2> --> SCM_SETAND_CXR (<e1>, <e2>) etc.
(Among other things, this change makes it easier to build Guile
with certain compilers which have problems with casted lvalues.)
integer (assuming for now accepting an integer is a good thing).
* error.c, fports.c: replace use of %S in lgh_error args with %s.
%S will be used instead for write'ing arguments.
* unif.c (scm_transpose_array): change arguments in the SCM_WNA
asserts. fix a few other asserts.
(scm_aind, scm_enclose_array, scm_array_in_bounds_p,
scm_uniform_vector_ref, scm_array_set_x,
scm_dimensions_to_unform_array): change args in
SCM_WNA SCM_ASSERTS and change scm_wta's to scm_wrong_num_args.
strop.c (scm_substring_move_left_x, scm_substring_move_right_x,
scm_substring_fill_x): likewise.
gsubr.c (scm_gsubr_apply): likewise.
eval.c (SCM_APPLY): likewise.
* eval.c (4 places): replace scm_everr with lgh_error or
scm_wrong_num_args.
* error.c, error.h (scm_wrong_num_args, scm_wrong_type_arg,
scm_memory_error): new procedures.
* scm_everr: deleted. can use scm_wta, dropping first two args.
scm_error: convert NULL subr to SCM_BOOL_F.
* __scm.h: don't define SCM_STACK_OVFLOW, SCM_EXIT, SCM_ARG6, SCM_ARG7,
SCM_ARGERR.
* stackchk.c (scm_report_stack_overflow): use lgh_error instead
of scm_wta.
* error.c, error.h: new error keys: scm_arg_type_key,
scm_args_number_key, scm_memory_alloc_key, scm_stack_overflow_key,
scm_misc_error_key.
scm_wta: reimplement using lgh_error instead of scm_everr.
wta for range errors (ASSERT still needs work).
* error.c, error.h (scm_out_of_range): new procedure.
* error.c, error.h (scm_out_of_range_key): new key.
* posix.c (scm_sync): #else was missing.
* error.c, error.h: append _key to names scm_num_overflow and
scm_system_error.
* __scm.h (SCM_SYSMISSING, SCM_NUM_OVERFLOW): use SCM_BOOL_F instead
of consing an empty list.
(SCM_SYSERROR etc.): move into error.c, make them procedures instead
of macros, saves code and string space.
error.c, fports.c, numbers.c, posix.c, ioext.c, filesys.c, socket.c,
fdsocket.c, simpos.c: change names of SCM_SYSERROR etc., to
lower case. Rename scm_syserror_m to scm_syserror_msg.
error.h: prototypes for new procedures.
