The definition and the declaration for scm_integer_from_mpz
do not match
* libguile/integers.c (scm_integer_from_mpz): takes const mpz_t arg
No callers need to be changed.
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
These are important for reliable networking, since they prevent network
operations from hanging indefinitely.
* libguile/socket.c (scm_init_socket): Define SO_RCVTIMEO and
SO_SNDTIMEO.
(scm_getsockopt, scm_setsockopt): Include SO_RCVTIMEO and SO_SNDTIMEO in
docstring and handle them.
* doc/ref/posix.texi (Network Sockets and Communication): Document them.

Avoids spurious "error in finalization thread: Success" messages when
the finalization pipe gets closed.
* libguile/finalizers.c (finalization_thread_proc): Return when 'data.n'
is zero.
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.
Fixes <https://bugs.gnu.org/55596>.
Reported by Hugo Nobrega <hugonobrega@ic.ufrj.br>
and Jack Hill <jackhill@jackhill.us>.
* libguile/posix.c (start_child): Close OUT only if it's greater than 2.
* test-suite/tests/posix.test ("system*")["exit code for nonexistent file"]
["https://bugs.gnu.org/55596"]: New tests.
The current socket address constructors all assume, that there are no
null bytes in the socket path. This assumption does not hold in Linux,
which uses an initial null byte to demarcate abstract sockets and
ignores all further null bytes [1].
[1] https://www.man7.org/linux/man-pages/man7/unix.7.html
* libguile/sockets.c (scm_fill_sockaddr)[HAVE_UNIX_DOMAIN_SOCKETS]:
Use scm_to_locale_stringn to construct c_address.
Use memcpy instead of strcpy and calculate size directly instead of
using SUN_LEN.
(_scm_from_sockaddr): Copy the entire path up to the limits imposed by
addr_size.
* test-suite/tests/00-socket.test: ("make-socket-address"): Add case for
abstract unix sockets.
("AF_UNIX/SOCK_STREAM"): Add abstract socket versions of bind, listen,
connect and accept.

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'.
* libguile/srfi-14.i.c: Update from Unicode 14.0.0.
* libguile/unidata_to_charset.pl (compute): Write arrays as static const
data, to avoid polluting the namespace and to avoid adding these to the
GC root set.
* libguile/srfi-14.c (SCM_CODEPOINT_F_IMMUTABLE): New flag.
(scm_charset_is_immutable): New internal predicate.
(SCM_VALIDATE_MUTABLE_CHARSET): New internal validator.
(cs_full_ranges, cs_full_ranges_len): Re-express as separate ranges and
len, because the ranges pointer in scm_t_char_set is mutable.
(scm_char_set_unfold_x, scm_list_to_char_set_x)
(scm_string_to_char_set_x, scm_char_set_filter_x)
(scm_i_ucs_range_to_char_set, scm_char_set_adjoin_x)
(scm_char_set_delete_x, scm_char_set_complement_x)
(scm_char_set_unfold_x, scm_char_set_intersection_x)
(scm_char_set_difference_x, scm_char_set_xor_x): Require mutable
charsets.
(define_charset): Add immutable flag.
(scm_init_srfi_14): Adapt initial charset definitions.
* libguile/numbers.c (log_of_shifted_double, scm_log10): Avoid complex
extension when the argument is a real nan.
* test-suite/tests/numbers.test: Tests for nans of either sign.
* libguile/numbers.c (scm_abs): As stated. When x is a nan with the sign bit
set, this changes the behavior of (magnitude x) back to what it was in 3.0.7,
to clear that bit.
* libguile/integers.c (scm_integer_abs_z): Just call
scm_integer_negate_z if negation is needed.
(scm_integer_sub_zz): Use mpz_sub instead of cloning bignum.
Calling out to Scheme was a performance regression.
* libguile/integers.h:
* libguile/integers.c (scm_integer_expt_ii, scm_integer_expt_zi): New
internal functions.
* libguile/numbers.c (scm_integer_expt): Go back to C. But, include
fast cases for inums and doubles.
* module/ice-9/boot-9.scm: Revert addition of integer-expt.
