Thanks.
I adjusted via the attached patch (the declaration
of getgrouplist is in <unistd.h>, and the "then"-block
should use gid_t), and tested: there was not even a
warning for the test program emitted by the "then"-block,
so same result as before:
lib/mgetgroups.c: In function 'mgetgroups':
lib/mgetgroups.c:70:32: error: pointer targets in passing argument 3
of 'getgrouplist' differ in signedness [-Werror=pointer-sign]
# define getgrouplist_gids(g) (g)
^
mgetgroups.m4.patch
