Merge GH interface library into libguile.
* gh.h, gh_data.c, gh_eval.c, gh_funcs.c, gh_init.c, gh_io.c,
gh_list.c, gh_predicates.c, gh_test_c, gh_test_c.c, gh_test_repl,
gh_test_repl.c: New files.
* Makefile.am (libguile_la_SOURCES): Add gh_data.c, gh_eval.c,
gh_funcs.c, gh_init.c, gh_io.c, gh_list.c, gh_predicates.c. Move
_scm.h to ...
(EXTRA_libguile_la_SOURCES): ... here.
(pkginclude_HEADERS): Add variable, to get gh.h installed.
(THREAD_LIBS, check_ldadd, check_PROGRAMS, gh_test_c_SOURCES,
gh_test_c_LDADD, gh_test_repl_SOURCES, gh_test_repl_LDADD):
New variables, describing how to build the gh test programs.
* configure.in: Check for -lm, -lsocket, -lnsl; we need this to
build the test programs, and we probably should have been linking
libguile.la against them all along, to support AIX shared libs.
Add cflags for threads to CFLAGS; add libs for threads to new
variable THREAD_LIBS, used in Makefile.am.
* ChangeLog-gh: log from old `gh' subdirectory.
* Makefile.in, configure, scmconfig.h.in: Rebuilt.
scm_status_term_sig, scm_status_stop_sig): Modified to work with
Ultrix versions of WIFSTOPPED, etc., which assume that their
arguments are lvalues (hmm).
* Makefile.am: Use lib_LTLIBRARIES instead of lib_PROGRAMS.
Use libguile_la_LIBADD instead of libguile_la_LDADD. (What's the
difference here?)
(libguile_la_SOURCES, modinclude_HEADERS, EXTRA_DIST): Format for
readability.
* Makefile.in: Rebuild.
* Makefile.am (EXTRA_libguile_la_SOURCES): add putenv.c.
* configure.in: move putenv from AC_CHECK_FUNCS to AC_REPLACE_FUNCS.
* putenv.c: new file, from sh-utils 1.12.
* posix.c (scm_environ): use malloc in place of scm_must_malloc
since allocation isn't for Scheme objects.
(scm_putenv): copy strings before placing in the environment.
* stime.c (scm_current_time): throw an error if time returns -1,
instead of returning #f.
(scm_get_internal_real_time, scm_get_internal_real_time): use
scm_long2num for return value instead of SCM_MAKINUM.
* stime.h: prototypes updated.
* stime.c (scm_time_in_msec): apparently unused, deleted.
* configure.in: check for gettimeofday.
* stime.c (scm_time_plus_ticks): new procedure, an scsh interface
which may be more usefully portable than a gettimeofday interface.
* stime.c (filltime): recovered static procedure.
(scm_localtime, scm_gmtime, scm_mktime, scm_tzset): recovered from
an earlier Guile.
* posix.h: add prototype for scm_close_pipe, remove prototypes for
scm_open_input_pipe, scm_open_output_pipe, change scm_mknod prototype.
* * posix.c (scm_mknod): split the mode argument into type and perms
arguments, like the extra fields returned by stat.
* fports.c (scm_pipob): set the close, free and print procedures.
(scm_close_pipe): new procedure.
* posix.c (scm_open_input_pipe, scm_open_output_pipe): deleted,
define them in boot-9.scm
wan't defined. Don't include fd.h.
* Previously fd.h was regenerated whenever configure was run,
forcing a couple of files to be recompiled.
* fd.h.in: deleted, SET_FILE_FD_FIELD moved to ioext.c.
* configure.in: AC_DEFINE FD_SETTER instead of HAVE_FD_SETTER.
Check for _fileno as well as _file.
Don't output fd.h.
* ioext.c: don't fd.h.
* acconfig.h: remove duplicate HAVE_FD_SETTER and change the
other to FD_SETTER.
* Change the stratigy for getting information about errno
(and now signal number) values, e.g., ENOSYS, SIGKILL. Instead of
generating lists of symbols during the build process, which will
not always work, include comprehensive lists in the distribution.
To help keep the lists up to date, the "check_signals" and
"check_errnos" make targets can be used.
* configure.in: don't check for a command to extract errno codes.
* Makefile.am: update file lists, remove errnos.list and errnos.c
targets, add cpp_err_symbols.c, cpp_sig_symbols.c, check_signals,
check_errnos targets.
(CLEANFILES): remove errnos.c and errnos.list, add
cpp_err_symbols_here cpp_err_symbols_diff cpp_err_symbols_new
cpp_sig_symbols_here cpp_sig_symbols_diff cpp_sig_symbols_new
* errnos.default: deleted.
* cpp_signal.c: new file.
* cpp_errno.c: renamed from errnos_get.c.
* cpp_err_symbols, cpp_sig_symbols: new files.
* cpp_cnvt.awk: renamed from errnos_cnvt_awk.
* error.c (scm_init_error): #include cpp_err_symbols instead of
errnos.c.
* posix.c (scm_init_posix): don't intern signal symbols. #include
cpp_sig_symbols.c.
* strop.c (scm_i_index): allow the lower bound to be equal to the
length of the string, so a null string doesn't always give an error.
* posix.h: new prototypes.
* posix.c (scm_status_exit_val, scm_status_term_sig,
scm_status_stop_sig): new functions, as in scsh. They break down
process status values as returned by waitpid.
(scm_freopen): use RO string macros for filename and modes.
(scm_duplicate_port, scm_fdopen): use RO string macros for modes.
* posix.c (scm_getgrgid): simplify conversion of name to C string.
(scm_mknod): use RO string macros for path.
* socket.c (scm_fill_sockaddr, scm_send, scm_sendto):
use SCM_ROSTRINGP, SCM_ROCHARS, SCM_ROLENGTH.
* net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv):
use SCM_ROSTRINGP and SCM_ROCHARS.
