Since Guile requires a C99 compiler, we can rely on signal handlers
returning void, not int.
* configure.ac: remove AC_TYPE_SIGNAL
* libguile/scmsigs.c (SIGRETTYPE): remove SIGRETTYPE
(take_signal): returns void
(scm_sigaction_for_thread): presumes handlers return void
This is the same strategy as used for the 'accept4' bindings introduced
in 6e0965104c.
* libguile/posix.c (scm_pipe): Rename to...
(scm_pipe2): ... this. Add an optional 'flags' parameter and honor it.
(scm_pipe): Rewrite as a call to 'scm_pipe2'.
* libguile/posix.h (scm_pipe2): New declaration.
* test-suite/tests/posix.test ("pipe"): New tests.
* configure.ac: Look for 'pipe2'.
* NEWS: Update.
Before the change ./configure incorrectly enabled -flto on toolchains
that support -flto on compiler side but don't support -flto on linker
side. This caused incorrect type size detection on nixpkgs' Darwin:
configure:54594: checking size of size_t
configure:54600: clang -std=gnu11 -o conftest -g -O2 -flto conftest.c >&5
ld: warning: ignoring file /private/tmp/nix-build-guile-3.0.8.drv-0/conftest-00e93d.o,

Taken from https://github.com/NixOS/nixpkgs/pull/160051#issuecomment-1046105041
The change makes sure -flto support tests basic support of just for
object file generation but for linker as well.

Fixes <https://issues.guix.gnu.org/54198>.
As noted in the comment at the top, 'SIZEOF_TYPE' must be used instead
of 'sizeof (TYPE)' to support cross-compilation.
The regression was introduced in
5e5afde06f but only became apparent with
717e787da6.
* libguile/gen-scmconfig.c (main): Replace uses of 'sizeof' by
references to the SIZEOF_* macros.
* configure.ac: Add 'AC_CHECK_SIZEOF' call for 'intmax_t'.
* configure.ac:
* Makefile.am (SUBDIRS): Replace bootstrap/ with stage0, stage1, and
stage2.
* am/bootstrap.am: Include all files and all rules.
* meta/build-env.in (GUILE_AUTO_COMPILE): Always turn off
auto-compilation. Take a GUILE_BOOTSTRAP_STAGE argument, which can be
stage0, stage1, stage2, or unset. Adapt the load-compiled path
accordingly.
* meta/uninstalled-env.in: Include .go files from stage2.
* module/Makefile.am: Rework to use boostrap.am.
* module/system/base/optimize.scm (available-optimizations): Punt the
inlinable-exports machinery to -O2.
* stage0/Makefile.am:
* stage1/Makefile.am:
* stage2/Makefile.am: New files.
* configure.ac: Check if the compiler supports link-time optimization.
If it does, turn it on. Saves around 15% off libguile binary size.
Controllable via --enable-lto configure option.
This suggests moving the conditional that determines if mini-gmp is used
into scmconfig.h.
* configure.ac: replace PKG_CHECK_MODULES for gmp with AC_LIB_HAVE_LINKFLAGS
Remove ENABLE_MINI_GMP define. Also don't run mpz_inits test for
--enable-mini-gmp.
* libguile/gen-scmconfig.c (main) [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
with SCM_I_GSC_ENABLE_MINI_GMP
* libguile/bytevectors.c [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
with SCM_ENABLE_MINI_GMP
* libguile/init.c [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
with SCM_ENABLE_MINI_GMP
* libguile/numbers.c: include scm.h
[SCM_ENABLE_MINI_GMP]: provide mpz_inits and mpz_clears
[ENABLE_MINI_GMP]: prefer SCM_ENABLE_MINI_GMP to ENABLE_MINI_GMP
* libguile/numbers.h: include scm.h
* libguile/random.c [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
with SCM_ENABLE_MINI_GMP
* libguile/socket.c [ENABLE_MINI_GMP]: replace ENABLE_MINI_GMP
with SCM_ENABLE_MINI_GMP
* NEWS: Update.
* am/bootstrap.am (SOURCES):
* module/Makefile.am (SOURCES): Add system/foreign-library.scm.
* configure.ac: Replace ltdl check with -ldl check.
* libguile/dynl.c: Rewrite to just expose core dlopen / dlsym / etc to a
helper Scheme module.
(scm_dynamic_link, scm_dynamic_pointer, scm_dynamic_function)
(scm_dynamic_object_p, scm_dynamic_call): Rewrite in terms of (system
foreign-library).
* libguile/extensions.c (load_extension): Avoid scm_dynamic_call.
* module/system/foreign-library.scm: New file.
* module/oop/goops.scm (<dynamic-object>): Hackily export
<foreign-library> instead of a class here.
* doc/ref/api-foreign.texi (Foreign Function Interface): Rewrite to only
document the new interfaces. Eventually we will deprecate
dynamic-link and friends.
* doc/ref/guile.texi (API Reference): Move Foreign Objects after Foreign
Function Interface. Seems there should be some closer relationship
but this will do for now.
* doc/ref/tour.texi (Putting Extensions into Modules):
* doc/ref/libguile-parallel.texi (Parallel Installations): Update for
rename of Modules and Extensions to Foreign Extensions.
* libguile/deprecated.h:
* libguile/deprecated.c (scm_dynamic_unlink): Deprecate.
* libguile/guile.c: Remove ltdl include.
* test-suite/tests/foreign.test: Update tests to use new API, and update
error expectations.
* configure.ac (AC_CHECK_FUNCS): add mkdtemp! test
* doc/ref/posix.texi: document mkdtemp!
* libguile/filesys.c (scm_mkdtemp_x): new function
* libguile/filesys.h: new declaration for scm_mkdtemp_x
* test-suite/tests/filesys.test: add tests for mkdtemp!
