This is for Emacs, which has its own allocator and where we don't want to use xalloc. * lib/group-member.c: Include xalloc-oversized.h, not xalloc.h, since we no longer use xmalloc. Do not include stdbool.h, since the changes below happen to remove the only use of bool. (GROUPBUF_SIZE): New constant. (struct group_info): Remove n_groups member. Add groupbuf member. This lets us get the groups without using malloc, usually. (free_group_info, get_group_info): Adjust to this. (get_group_info): Return the number of groups found, or -1 on error. Use plain malloc not xmalloc, and treat its failure as if there are no groups, as the user already loses in case of error. (group_member): Simplify, based on changes to get_group_info. * modules/group-member (Depends-on): Remove dependencies on xalloc and stdbool. Add dependency on xalloc-oversized.
