* load.c (scm_search_path): Make max_path_len and max_ext_len
unsigned, since they're compared against string sizes.
* load.c (init_build_info): Make i unsigned.
Added #include "objects.h"
* eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
Add #include "feature.h".
* ports.h (SCM_EOF_OBJECT_P): New macro predicate.
This test is needed at many places in the code and should be
abstracted. (Motivated by the need of this test in libguiletk.)
* ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
(scm_eval_string), load.c (scm_primitive_load,
scm_read_and_eval_x), gh_eval.c (gh_eval_str):
Use SCM_EOF_OBJECT_P.
* eval.c (scm_init_eval): Add feature `delay'.
Makefile directory variables. Print a message, but don't print
all the commands.

* load.c: #include "alist.h".
(init_build_info): New function.
(scm_init_load): Call it.
* Makefile.in: Regenerated.
* gdbint.c (gdb_read): update scm_lreadr usage.
* load.h: update prototypes.
* load.c (scm_primitive_load, scm_read_and_eval_x,
scm_primitive_load_path): remove case_insensitive_p, sharp arguments.
* read.h: add prototype for scm_read_hash_extend. Change args for
other prototypes.
* read.c (scm_read_hash_procedures): new variable.
(scm_read_hash_extend): new procedure.
(scm_get_hash_procedure): new procedure.
* (scm_lreadr): use scm_get_hash_procedure instead of an argument
for extended # processing.
(scm_read, scm_lreadr, scm_lreadrecparen, scm_lreadparen,
scm_read_token): remove case_i, sharp arguments. Change callers.
* read.h (SCM_N_READ_OPTIONS): increase to 3.
(SCM_CASE_INSENSITIVE_P): define.
* read.c: add case-insensitive option to scm_read_opts.
* (scm_read_token): use SCM_CASE_INSENSITIVE_P instead of an argument
to determine whether to convert symbol case.
(default_case_i): definition removed.
* read.c (scm_read_token): if case_i, downcase ic before doing
anything with it.
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.
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.
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.
* 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.)
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.
declare the char * to be const. Avoids a warning in rgx.c.
* ports.h: spelling fix.
* filesys.c (scm_sys_stat, scm_sys,lstat): include file name in
error messages.
* load.c (scm_sys_try_load_path): throw an error if file not found
(like it says it in NEWS).
by scm_open_file is #f, it won't be. Always return SCM_UNSPECIFIED.
Change the Scheme name from %try-load to primitive-load.
* error.c (scm_error): convert a NULL message to SCM_BOOL_F.
Can avoid passing a message, allowing it to be derived in the
error handler (e.g., if we want to throw to the key both from
Scheme and C).
Move code to initialize and search %load-path from ice-9 to C
code, so we can use the load-path to find the ice-9 boot code;
this makes it easier to run Guile without installing it. See
corresponding changes in guile/Makefile.in.
* feature.c: Move stuff concerned with the load path to load.c.
(scm_compiled_library_path): Deleted.
Don't #include libpath.h here.
* feature.h: Don't mention scm_compiled_library_path.
* load.c: #include "libpath.h" here, as well as <sys/types.h>,
<sys/stat.h>, and <unistd.h> (if present).
(R_OK): #define if the system hasn't deigned to.
(scm_loc_load_path): New variable.
(scm_init_load_path, scm_sys_search_load_path,
scm_sys_try_load_path): New functions.
(scm_init_load): Initialize scm_loc_load_path to point to the
value cell of the Scheme %load-path variable.
* load.h: Add declarations for scm_sys_search_load_path,
scm_sys_try_load_path.
* init.c: Call scm_init_load_path.
* Makefile.in (feature.o, load.o): Dependencies updated.
* load.c, load.h: Rewrite using PROTO macro.
