#define _POSIX_SOURCE before #including it.
* aclocal.m4 (GUILE_STRUCT_UTIMBUF): New test.
* acconfig.h: New comment text for above CPP symbol.
* configure.in: Call it.
* posix.c: #define _POSIX_SOURCE if it seems necessary.
* configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h
in the list.
* posix.c: Check HAVE_SYS_UTIME_H and HAVE_UTIME_H, instead of
testing for __EMX__.
* posix.c: #include <libc.h>, if it exists.
* posix.c: Cast the return result to GETGROUPS_T, not gid_t; we
don't even know if the latter exists.
* posix.c (s_sys_setpgid, s_sys_setsid, s_sys_ctermid,
s_sys_tcgetpgrp, s_sys_tcsetpgrp): Renamed from s_setpgid,
s_setsid, s_ctermid, s_tcgetpgrp, s_tcsetpgrp, for consistency.
* posix.c (R_OK, W_OK, X_OK, F_OK): #define these if the system's
header files don't.
(scm_init_posix): Use them when initializing the Scheme constants
of the same name.
#define _POSIX_SOURCE before #including it.

* acconfig.h: New comment text for above CPP symbol.
* configure.in: Call it.
* posix.c: #define _POSIX_SOURCE if it seems necessary.
* configure.in (AC_CHECK_HEADERS): Include sys/utime.h and utime.h

autoconf-supplied values, instead of deriving them ourselves.
(pkgincludedir, datadir, pkgdatadir): New variables.
(install, uninstall): Put the header files in a special
subdirectory, not in the main search path.
* Makefile.in (IMPLPATH): Deleted; never used.
* Makefile.in (TCL_SRC_DIR, TK_SRC_DIR): Deleted; we don't depend
on the Tcl/Tk source any more.
(INCLUDE_CFLAGS): Remove references to the above.
* Makefile.in (version.o): Corrected dependencies.
array; use it appropriately. Since GCC is quite happy to
subscript functions, it never warned us about this; we should use
-Wpointer-arith in the future. I guess we never tested
case-insensitivity.
* Makefile.in (c_files): add strerror.c.
* strerror.c: new file from Emacs' sysdep.c.
maybe configure should also check for sys_errlist.
* configure.in (AC_REPLACE_FUNCS): add strerror.
(Mostly prefixing with SCM_.) Renamed "debug-options" -->
"debug-options-interface". See commentary in options.c.
* options.h, options.c: Options now have documentation strings.
Also added a long explanatory commentary.
scm_object_properties shouldn't return handle. `handle' now gets
initialized in scm_set_object_properties_x. scm_object_properties
doesn't any longer create an entry in scm_object_whash.
argument pairs. Extensive modifications to the debugging
evaluator. Added "SECTION:" commentaries to clarify what happens
when, during double compilation. Renamed EVALIMP --> EVALIM.
Renamed EVAL --> XEVAL. Removed function evalcar. Defined
evalcar to scm_eval_car. Added explanation of "EVAL" symbols to
the beginning of the file. New procedure: scm_unmemocopy.
Added some global state variables needed by the debugging
evaluator: scm_ceval_ptr, last_debug_info_frame, debug_mode,
check_entry, check_apply, check_exit, debug_options and
evaluator_traps. New acro: undefine.
