Motivation: This is system specific code which is related to file
I/O. It also may use select. Added code by Gary Houston to
detect presence of character in stdio buffers.
* guile-snarf.sh: New file.
* Makefile.in (inner_h_files): Added snarf.h
(ancillary, install, uninstall, distclean): Added actions for
guile-snarf.
(.c.x): Use guile-snarf.
(guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
(gen_c_files): Note that these depend on guile-snarf.
* _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
now in "snarf.h". Added #include "snarf.h" to get them.
* configure.in: Added guile-snarf to AC_OUTPUT
* libguile.h: Added #include "snarf.h".
(Patches applied and tweaked by Jim Blandy.)
scheme name from "int?" to "integer?". It seems to do the job.
* numbers.h: Rename prototype too.
* scmhob.h (intp): Change definition to refer to scm_integer_p. I
hope this is right.

* scmhob.h (intp): Change definition to refer to scm_integer_p. I
hope this is right.
* * numbers.c (scm_less_p, scm_gr_p, scm_leq_p, scm_geq_p,
scm_num_eq_p): Rename these according to R4RS conventions: call
them <, <=, =, >, and >=, not <?, <=?, =?, >?, and >=?. En route
to making libguile R4RS compliant without ice-9...
extensions listed in the %load-extensions variable. If FILENAME
is absolute, return it unchanged, without searching the load path.
* (scm_loc_load_extensions): New variable, pointing to
%load-extensions' value cell.
(scm_init_load): Initialize it, and the value it points to.
(scm_primitive_load_path): Improve error reporting.
* * load.c (scm_loc_load_hook): New variable, pointing to value cell
of new Scheme variable %load-hook.
(scm_primitive_load): Apply %load-hook to filename.
is available in a FILE structure, which is needed by char-ready.
* acconfig.h: define FILE_CNT_FIELD, FILE_CNT_GPTR and
FILE_CNT_READPTR.
* simpos.c (scm_getenv): renamed from scm_sys_getenv. Throw
exceptions using misc_error instead of syserror. It seems a bit
odd to throw an exception if a string can't be found in the
environment, but it's consistent with open-file, stat etc.
(simpos.h): remove sys_ from getenv.
* posix.c (scm_putenv): renamed from scm_sys_putenv. If an error
occurs, throw an error instead of returning errno. Return value
is now unspecified.
(numerous in posix.c and posix.h): removed superfluous sys_ from names.
the stat mode and append them to the returned vector.
There isn't much overhead in doing this and it avoids the need to
work with S_IRUSR et al. in Scheme.
Define symbols scm_sym_regular etc.
(scm_init_filesys): don't intern S_IRUSR etc.
and s_primitive_load_path.
* eval.c, load.c, error.c (scm_wta): use scm_misc_error.
* error.h: don't declare error symbols. prototype for scm_misc_error.
* stackchk.c (scm_stack_overflow_key): defined here instead of in
error.c.
* error.c: use SCM_SYMBOL to set up error keys.
scm_misc_error: new procedure.
initialization procedure.
- Delete in, out, err arguments; there are other perfectly good
ways to override these when desired.
- Delete result argument; this function shouldn't ever return.
- Rename init_func argument to main_func, for less confusion.
- Delete boot_cmd argument; main_func is more general.
-Add 'closure' argument, to help people pass data to main_func
without resorting to global variables.
- Abort if reentered; don't bother returning an error code.
- Call scm_init_standard_ports to set up the default/current
standard ports; no need to pass them to scm_start_stack.
- Remove code to evaluate the boot_cmd, and start the repl; let
the user do something like that in main_func if they want.
- Remove code to package up a return value; main_func can do any
of that as needed.
- Call exit (0), instead of returning.
(scm_start_stack): Don't initialize the I/O ports here; that's
weird. Delete in, out, err arguments. Move guts to
scm_init_standard_ports, scm_stdio_to_port.
(scm_init_standard_ports): New function, to set up current and
default standard ports.
(scm_start_stack, scm_restart_stack): Make these static.
* init.h (scm_boot_guile): Adjust declaration.
(scm_start_stack, scm_restart_stack): Remove externally
visible declarations for these.
(enum scm_boot_status): Removed; now scm_boot_guile never returns.
(scm_boot_guile): Call scm_set_program_arguments here, later than
the old initialization.
* init.c: (scm_boot_guile, scm_boot_guile_1): New, simplified
initialization procedure.

(Among other things, this change makes it easier to build Guile
with certain compilers which have problems with casted lvalues.)
ramap.c, symbols.c: Added new selectors SCM_CARLOC and SCM_CDRLOC
for obtaining the address of a car or cdr field. Motivation:
&SCM_CXR make assumptions about the internal structure of the
SCM_CXR selectors.

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.

(scm_unmemoize, scm_memoized_environment): Bugfix: Check for
SCM_NIMP before applying heavier predicates in argument checking.
(scm_local_eval): Also take memoized object as argument.
a stack object. Introduce one level of indirection in the stack
object to make it possible to "narrow" to a certain region of the
stack. This facilitates making use of more clever algorithms (not
implemented) for selecting relevant frames and gives a cleaner
design since selection of frames can be done independently of
extraction of frames from the real stack.
(scm_stack_id): Also take #t as argument which means look at
current stack.
from scm_sys_try_load and scm_sys_try_load_path. The Scheme name
of scm_primitive_load_path was also changed to
"primitive-load-path", from "%try-load-path". Callers changed.
We'd like to respect the convention that a function named
"try-mumble" should behave just like the function called "mumble",
but return #f instead of signalling some error.
* load.h: Rename prototypes.
the print state representation: Don't use a tail array for
recording of circular references. Resizing of the print state
structure invalidates the print state pointer. To avoid passing
around an indirect print state reference to all printing
functions, we instead let the print state reference a resizable
vector.
