See include/unistd.h #ifdef _GNU_SOURCE int brk(void *); void *sbrk(intptr_t); pid_t forkall(void); int vhangup(void); int getpagesize(void); int usleep(unsigned); unsigned ualarm(unsigned, unsigned); int setgroups(size_t, const gid_t []); int setresuid(uid_t, uid_t, uid_t); int setresgid(gid_t, gid_t, gid_t); char *get_current_dir_name(void); #endif Most of the above according to their man pages should be defined if _BSD_SOURCE is set. Should the headers be filled with feature checks (that would make them quite ugly) or assume we have _GNU_SOURCE defined and remove any _GNU_SOURCE checks? -- Georgi Chorbadzhiyski http://georgi.unixsol.org/
