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.
File is now empty; deleted.
* files.h: Deleted.
* filesys.c: scm_sys_delete_file is now here. Remove
#if's; they seem to rely on remnants of an old portability
regimen. If the problems come up again, solve them properly,
using autoconf. Specifically: Don't test M_SYSV, and #define
remove to be unlink if it's #defined; don't use remove just
because HAVE_STDC_HEADERS is #defined.
* filesys.h: Add declarations for scm_sys_delete_file.
* Makefile.in (libobjs, inner_h_files, c_files, gen_c_files): Omit
files.o, files.h, files.c, and files.x.
* init.c: Don't #include "files.h", and don't call scm_init_files.
* configure.in: Call AC_TYPE_MODE_T.
(AC_CHECK_HEADERS): Add libc.h, to get more prototypes on the
NeXT. Put header file list in alphabetical order.
* configure, scmconfig.h.in: Regenerated.
* filesys.c [HAVE_LIBC_H]: #include <libc.h>.
* filesys.c [HAVE_STRING_H]: #include <string.h>, to get prototype
for strerror.
