* libguile/r6rs-ports.c (scm_get_bytevector_n, scm_get_bytevector_n_x,
scm_get_bytevector_some, scm_get_bytevector_all): Avoid peeking for
EOF when we already know.
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'.

feature.
* module/Makefile.am (SCRIPTS_SOURCES): Make `scripts/autofrisk.scm' and
`scripts/scan-api.scm' conditional on `BUILD_ICE_9_POPEN'.

macro.
(mpz_inits, mpz_clears)[!HAVE_DECL_MPZ_INITS]: New functions.
* configure.ac: Check for the declaration of `mpz_inits'.
In response to <http://bugs.gnu.org/13958>.
Reported by Lluís Batlle i Rossell <viric@viric.name>.
* doc/ref/posix.texi (Network Databases): Document the missing errno
value for EAI_SYSTEM.

* libguile/numbers.c (exact_integer_is_perfect_square,
exact_integer_floor_square_root): New static functions.
(scm_sqrt): Use SCM_LIKELY. Add 'scm_t_inum' variable in inum case to
reduce the number of uses of SCM_I_INUM. Rename 'mpz_t' variable.
Remove unneeded sign check. Handle bignums too large to fit in a
double. Handle fractions too large or too small to fit in a
normalized double.
* test-suite/tests/numbers.test ("sqrt"): Add tests.
* libguile/numbers.c (scm_sqrt): Handle exact integers and rationals in
such a way that exact results are returned whenever possible.
* test-suite/tests/numbers.test ("sqrt"): Add tests.
* libguile/numbers.c (idbl2str): Print large numbers in scientific
notation only if the exponent is >= 7 and the least significant
non-zero digit has value >= radix^4.
* test-suite/tests/numbers.test ("number->string"): Add tests.
* libguile/r6rs-ports.c (scm_get_bytevector_some, scm_get_bytevector_n,
scm_get_bytevector_n_x, scm_get_bytevector_all): Use
`scm_get_byte_or_eof' and `scm_peek_byte_or_eof' instead of their
`char' counterparts.
Reported by Chris K. Jester-Young.
Fixes <http://bugs.gnu.org/13757>.
* libguile/numbers.c (idbl2str): Reimplement.
(mem2decimal_from_point): Accept negative exponents larger than
SCM_MAXEXP that produce subnormals.
(SCM_MAX_DBL_PREC): Removed preprocessor macro.
(scm_dblprec, fx_per_radix): Removed static variables.
(init_dblprec, init_fx_radix): Removed static functions.
(scm_init_numbers): Remove initialization code for 'scm_dblprec'
and 'fx_per_radix'.
* test-suite/tests/numbers.test ("number->string"): Restore tests that
previously failed. Remove comments about problems in the number
printer that are now fixed.
* libguile/numbers.c (scm_i_divide2double): New function.
(scm_i_divide2double_lo2b): New variable.
(scm_i_fraction2double, log_of_fraction): Use 'scm_i_divide2double'.
(do_divide): Removed. Its code is now in 'scm_divide'.
(scm_divide2real): Removed. Superceded by 'scm_i_divide2double'.
(scm_divide): Inherit code from 'do_divide', but without support for
forcing a 'double' result (that functionality is now implemented by
'scm_i_divide2double'). Add FIXME comments in cases where divisions
might not be as precise as they should be.
(scm_init_numbers): Initialize 'scm_i_divide2double_lo2b'.
* test-suite/tests/numbers.test (dbl-epsilon-exact, dbl-max-exp): New
variables.
("exact->inexact"): Add tests.
("inexact->exact"): Add test for largest finite inexact.
* libguile/numbers.c (scm_inexact_to_exact): Implement conversion of a
double to an exact rational without using the mpq functions.
* test-suite/tests/numbers.test (dbl-mant-dig): Simplify initializer.
(dbl-epsilon, dbl-min-exp): New variables.
("inexact->exact"): Add tests. Fix broken "2.0**i to exact and back"
test, and change it to "2.0**i to exact", to avoid use of
'exact->inexact'.
* libguile/numbers.c (log_of_exact_integer_with_size): Removed.
(log_of_exact_integer): Handle bignums too large to fit in a double
using 'scm_i_big2dbl_2exp' instead of 'scm_integer_length' and
'scm_ash'.
(log_of_fraction): Use 'log_of_exact_integer' instead of
'log_of_exact_integer_with_size'.
* libguile/numbers.c (scm_i_big2dbl_2exp): New static function.
(scm_i_big2dbl): Reimplement in terms of 'scm_i_big2dbl_2exp',
with proper rounding.
* test-suite/tests/numbers.test ("exact->inexact"): Add tests.

floor_right_shift_exact_integer, round_right_shift_exact_integer): New
static functions.
(scm_round_ash): New procedure.
(scm_ash): Reimplement in terms of 'left_shift_exact_integer' and
'floor_right_shift_exact_integer'.
* libguile/numbers.h: Add prototype for scm_round_ash. Rename the
second argument of 'scm_ash' from 'cnt' to 'count'.
* test-suite/tests/numbers.test (round-ash, ash): Add new unified
testing framework for 'ash' and 'round-ash'. Previously, the tests
for 'ash' were not very comprehensive; for example, they did not
include a single test where the number to be shifted was a bignum.
* doc/ref/api-data.texi (Bitwise Operations): Add documentation for
'round-ash'. Improve documentation for `ash'.
* libguile/posix.c (scm_execl, scm_execlp, scm_execle)
(scm_open_process): Remove casts for ancient mingw.
(scm_utime): If we fall back to utime, assert that flags is 0.
(scm_getlogin): Rely on gnulib.
* libguile/iselect.h: If we do not have sys/select.h, don't provide
scm_std_select, SELECT_TYPE, FD_SET, FD_ZERO, FD_ISSET, or FD_CLR.
Guile should not be setting these macros in public API. This is an
incompatible change on mingw, but oh well.
* libguile/threads.c: Rely on gnulib's select, and use that to implement
scm_std_select.
* libguile/deprecated.h:
* libguile/deprecated.c: Only provide scm_internal_select if we have
sys/select.h.
* libguile/posix.c: Reorder includes to fix mingw include-order
problem. Remove ttyname shims; gnulib is the place to fix that.
Remove winsock2 include, as gnulib seems to handle that OK. Rely on
the new pipe-posix gnulib module. Don't bother shimming getlogin, etc
on mingw; gnulib is the place for shims.
* libguile/fports.c: Reorder includes to put system includes first;
fixes windows/winsock2 include error problem. Rely on Gnulib's
select module.
(fport_input_waiting): Use select instead of scm_std_select.
* configure.ac (alarm): Check for decl.
* libguile/scmsigs.c: Reorder includes to put system includes first.
Fixes include order on mingw. Remove #define for alarm, as we will
use HAVE_DECL_ALARM. Remove #defines for sleep and usleep, as they
are not used.
(scm_alarm): Only define if HAVE_DECL_ALARM.
* libguile/socket.c (scm_init_socket): Remove mingw-specific code.
* libguile/fports.c: Remove ftruncate redefine; mingw is fine.
(scm_i_fdes_to_port): If we have no F_GETFL, just do an fstat. The
right place for an F_GETFL replacement would be in gnulib.
(fport_input_waiting): Remove an outdated comment.
* libguile/error.c (SCM_I_STRERROR, SCM_I_ERRNO): Remove, replacing uses
with strerror and errno.
* libguile/win32-socket.c:
* libguile/win32-socket.h: Remove. Mingw has suitable replacements.
* configure.ac:
* libguile/Makefile.am (EXTRA_libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES):
(noinst_HEADERS): Update for win32-socket removal.
* libguile/win32-socket.h:
* libguile/win32-socket.c (getservent, endservent, setservent)
(getprotoent, endprotoent, setprotoent): Remove mingw32 wrappers.
Their place is in gnulib, if anywhere.
Fixes <http://bugs.gnu.org/11887>.
* libguile/numbers.c (mem2ureal): New argument 'allow_inf_or_nan'.
Accept infinities and NaNs only if 'allow_inf_or_nan' is true and "#e"
is not present. Check for "inf.0" or "nan." case-insensitively. Do
not accept rationals with zero divisors.
(mem2complex): Pass new 'allow_inf_or_nan' argument to 'mem2ureal',
which is set if and only if a explicit sign was present.
* test-suite/tests/numbers.test ("string->number"): Add tests.
* libguile/vm.c (initialize_default_stack_size): New helper.
(scm_bootstrap_vm): Call initialize_default_stack_size.
* doc/ref/guile-invoke.texi (Environment Variables): Add docs.
