#serial 1
dnl From Jim Meyering.
dnl If you use this macro in a package, you should
dnl add the following two lines to acconfig.h:
dnl /* Define to rpl_getgroups if the replacement function should be used. */
dnl #undef getgroups
dnl
AC_DEFUN(jm_FUNC_GETGROUPS,
[AC_REQUIRE([AC_TYPE_GETGROUPS])dnl
AC_REQUIRE([AC_TYPE_SIZE_T])dnl
AC_CACHE_CHECK([for working getgroups], jm_cv_func_working_getgroups,
[AC_TRY_RUN([
int
main ()
{
/* On Ultrix 4.3, getgroups (0, 0) always fails. */
exit (getgroups (0, 0) == -1 ? 1 : 0);
}
],
jm_cv_func_working_getgroups=yes,
jm_cv_func_working_getgroups=no,
dnl When crosscompiling, assume getgroups is broken.
jm_cv_func_working_getgroups=no)
