Last change on this file since a5cb673 was a5cb673, checked in by Joel Sherrill <joel.sherrill@…>, on Apr 6, 1998 at 4:26:53 PM

Reordered CFLAGS definition so CFLAGS_DEFAULT is before
CFLAGS_$(TARGET_VARIANTS). This makes sure that -Wall appears
before any individual warnings are disabled during "debug" builds.
