Code Activity

Update Gnulib to v0.1-5703-g356a414e8c and add 'posix_spawn' module.

Browse source 
This is a followup to edfca3b7e5, which
added the 'posix_spawnp' module but not 'posix_spawn'.

* m4/gnulib-cache.m4: Add 'posix_spawn' module.
* gnulib-local/m4/clock_time.m4.diff: Adjust.
* configure.ac: Move 'gl_EARLY' use right after 'AC_PROG_CC'.

dnl is like AC_CHECK_FUNCS([func]), taking into account a portability problem
dnl on Android.
dnl Namely, if func was added to Android API level, say, 28, then the libc.so
dnl has the symbol func always, whereas the header file <foo.h> declares func
dnl conditionally:
dnl #if __ANDROID_API__ >= 28
dnl ... func (...) __INTRODUCED_IN(28);

dnl Thus, when compiling with "clang -target armv7a-unknown-linux-android28",
dnl the function func is declared and exists in libc.

# Subroutine of AC_SYS_YEAR2038. Probe for time_t that can represent
# time points more than 2**31 - 1 seconds after the epoch (dates after
# 2038-01-18, see above) and set the cache variable ac_cv_sys_year2038_opts
# to one of the values in the _AC_SYS_YEAR2038_OPTIONS list, or to
# "support not detected" if none of them worked. Then, set compilation
# options and #defines as necessary to enable large time_t support.
#
# Note that we do not test whether mktime, localtime, etc. handle
# large values of time_t correctly, as that would require use of
# AC_TRY_RUN. Note also that some systems only support large time_t
# together with large off_t.
#
# If support is not detected, the behavior depends on which of the
# top-level AC_SYS_YEAR2038 macros was used (see below).
#
# If you change this macro you may also need to change
# _AC_SYS_YEAR2038_OPTIONS.
