On AIX there is the following warning in a testdir of all modules:
test-pselect.c:23:18: warning: initialization of 'int (*)(int, fd_set *
restrict, fd_set * restrict, fd_set * restrict, const struct timespec
* restrict, const sigset_t * restrict)' from incompatible pointer type
'int (*)(int, void * restrict, void * restrict, void * restrict, const
struct timespec * restrict, const sigset_t * restrict)'
[-Wincompatible-pointer-types]
23 | SIGNATURE_CHECK (pselect, int,
| ^~~~~~~
It was documented in 2021 that this occurs when _ALL_SOURCE is defined
and I confirmed this was still the case in sys/time.h on
AIX 7.3 (cfarm119).
In that testdir _ALL_SOURCE was defined from extensions.m4. Since any
testdir with pselect will have _ALL_SOURCE defined I have disabled the
signature check:
$ gnulib-tool --extract-recursive-dependencies pselect | grep extension
extensions
extensions-aix
