* configure.ac: Check for __sincos.
* libguile/numbers.c (scm_c_make_polar): Fall back to __sincos if
possible. Fixes zero signedness of make-polar on macOS.
* libguile/filesys.c:
* configure.ac: Remove readdir_r / readdir64_r checks and usage.
glibc's impls are thread-safe, the _r variants are squirrely and now
deprecated in glibc, and it is expected that POSIX will mandate that
readdir{,64} be thread-safe already. See
https://sourceware.org/ml/libc-alpha/2016-02/msg00093.html.
* configure.ac: Add -std=gnu11 if the compiler is GCC (or clang). This
prevents AC_PROG_CC_C99 from downgrading us by adding -std=gnu99.
Fixes regression whereby we were always using the fallback
implementation of atomics.
* configure.ac: Require C99 or later. Emacs does, therefore so can
we. Note that by default GCC compiles in "gnu11" mode these days, and
this declaration doesn't change that.
* configure.ac: Check for getuid, getgid, setuid, and setgid.
* libguile/posix.c (scm_getuid, scm_getgid, scm_setuid, scm_setgid):
Only provide Scheme functions if the OS provides these facilities.
(scm_geteuid, scm_getegid, scm_seteuid, scm_setegid): Provide if the
host has getuid, getgid, etc, instead of being in a MinGW guard.
Based on a patch by Andy Stormont <astormont@racktopsystems.com>.
* configure.ac: Check for strtod_l.
* libguile/i18n.c (scm_locale_string_to_integer): Fix style.
(scm_locale_string_to_inexact): Check for strtod_l.
* am/bootstrap.am: New file, factored out of bootstrap/Makefile.am.
* bootstrap/Makefile.am: Use bootstrap.am.
* prebuilt/Makefile.am:
* prebuilt/i686-pc-linux-gnu/Makefile.am:
* prebuilt/mips-unknown-linux-gnu/Makefile.am:
* prebuilt/x86_64-unknown-linux-gnu/Makefile.am: New files.
* configure.ac: Output the prebuilt/ makefiles.
* Makefile.am: Descend into prebuilt/ when making dist.
* meta/uninstalled-env.in: Arrange to put prebuilt/ in the beginning of
the GUILE_LOAD_COMPILED_PATH. Also fix a case where bootstrap/ wasn't
being correctly added to the load path.
This reduces total build time to around 30 minutes or so.
* Makefile.am (SUBDIRS): Visit bootstrap/ before module/.
* bootstrap/Makefile.am: New file.
* configure.ac: Generate bootstrap/Makefile.
* meta/uninstalled-env.in (top_builddir): Add bootstrap/ to the
GUILE_LOAD_COMPILED_PATH.
* module/Makefile.am: Simplify to just sort files in alphabetical order;
since bootstrap/ was already compiled, we don't need to try to
optimize compilation order. Although the compiler will get faster as
more of the compiler itself is optimized, this isn't a significant
enough effect to worry about.
* configure.ac: Remove meta/guile-2.0.pc and
meta/guile-2.0-uninstalled.pc from 'AC_CONFIG_FILES'.
* meta/Makefile.am (substitute): New variable.
(guile-2.0.pc, guile-2.0-uninstalled.pc): New targets.
(guile-config, guild): Use $(substitute) instead of duplicated sed
script.
(CLEANFILES): Add the .pc files.
* meta/guile-2.0.pc.in (bindir, guild, guile): New variables.
* doc/ref/libguile-parallel.texi (Parallel Installations): Document the
'guild' and 'guile' pkg-config variables.
Reported by Sylvain Beucler <beuc@beuc.net>.
* configure.ac: Check for 'pthread_cancel'.
* libguile/threads.c (scm_cancel_thread): Conditionalize on
!SCM_USE_PTHREAD_THREADS || defined HAVE_PTHREAD_CANCEL.
* test-suite/tests/threads.test (require-cancel-thread): New procedure.
("timed joining fails if timeout exceeded", "join-thread returns
timeoutval on timeout", "cancel succeeds", "handler result passed to
join", "can cancel self"): Use it.
* configure.ac: Add -fwrapv when using GCC (or compatible), if
supported.
* libguile/numbers.h (SCM_I_MAKINUM): Cast to scm_t_bits (unsigned)
before shifting, to avoid undefined behavior.
* configure.ac: Remove checks for pipe, stftime, times, and select, as
our Gnulib modules already ensure they are provided.
* libguile/stime.c: Rely on gnulib providing `times'.
Fixes <http://bugs.gnu.org/13848>.
Reported by Jan Schukat <shookie@email.de>.
* configure.ac: Rename `HAVE_FORK' conditional to `BUILD_ICE_9_POPEN'.
Set it when both $enable_posix and $ac_cv_func_fork are true.
* libguile/posix.c (scm_init_posix): Add the `fork' feature.
* doc/ref/api-options.texi (Common Feature Symbols): Add `fork'.
* doc/ref/posix.texi (Pipes): Add footnote mentioning the `fork'
feature.
* module/Makefile.am (SCRIPTS_SOURCES): Make `scripts/autofrisk.scm' and
`scripts/scan-api.scm' conditional on `BUILD_ICE_9_POPEN'.
* test-suite/tests/popen.test (if-supported): New macro.
Wrap body in `if-supported'.
* m4/gnulib-cache.m4: Add `time'.
* lib/Makefile.am: Update, still from v0.0-7865-ga828bb2.
* configure.ac: Remove check for `struct timespec', which was redundant
with Gnulib, and conflicted with pthread-win32's <pthread.h>:
<http://lists.gnu.org/archive/html/bug-gnulib/2013-03/msg00096.html>.
* libguile/numbers.c (VARARG_MPZ_ITERATOR)[!HAVE_DECL_MPZ_INITS]: New
macro.
(mpz_inits, mpz_clears)[!HAVE_DECL_MPZ_INITS]: New functions.
* configure.ac: Check for the declaration of `mpz_inits'.
* configure.ac: Check for <sys/sendfile.h> and `sendfile'.
* libguile/filesys.c (scm_sendfile): New function.
* libguile/filesys.h (scm_sendfile): New declaration.
* test-suite/tests/filesys.test ("sendfile"): New test prefix.
* doc/ref/posix.texi (File System): Document `sendfile'.
* configure.ac: Remove `doc/ref/effective-version.texi' from the
`AC_CONFIG_FILES'.
* doc/ref/Makefile.am ($(srcdir)/effective-version.texi): New target.
