* sysdeps/mach/hurd/group_member.c: New file. * sysdeps/generic/group_member.c: New file. * Makerules (lib-noranlib): Don't depend on $(install-lib). (others): Do. * extra-lib.mk: Fix test of $(lib)-no-lib-dep. Mon Oct 30 12:33:10 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * Rules (others): Depend on $(extra-objs). * posix/unistd.h [__USE_GNU]: Declare group_member, __group_member. * posix/Makefile (routines): Add group_member. * sysdeps/posix/euidaccess.c: New file, adapted from fileutils. * sysdeps/unix/sysv/linux/i386/sigaction.c: Tighten constraint for SIG operand in asm so it must be a register. Add dead return to quiet gcc warning. * Makerules (sysd-rules): Write a defn for sysd-rules-done. [! sysd-rules-done]: Inhibit deps.
