Sat Sep 7 18:41:17 1996 Richard Henderson <rth@tamu.edu> * Makeconfig (+link): Filter out start, pre & postinit from the generic depenancies as well. * Rules: Add start, pre & postinit to the dependancies of $(others) and $(tests). * configure.in: elf_dirs missing "sysdeps" component. * locale/Makefile (distribute): Add locale.c and localedef.c.
