Last change on this file since a110b68 was a110b68, checked in by Joel Sherrill <joel.sherrill@…>, on Feb 18, 1999 at 5:55:49 PM

Part of automake VI patch from Ralf Corsepius <corsepiu@…>:

2) rtems-rc-19990131-1.diff

Rework of compilers/*.cfg files (esp. gcc-target-default.cfg) to adapt
the flags/makefile variables to automake and make standards (cf.
make.info - implicit rules/variables).

This patch is rather risky and may probably break things, but is an
essential step towards automake.

FWIW: It also reverts the i386-ASMFLAGS/ASFLAGS-patch, which was wrong,
as I had to experience ;-.
