From: dos-reis <gdr@axiomatics.org>
Date: Sun, 15 Aug 2010 04:51:44 +0000
Subject: 	* config/var-def.mk (CPPFLAGS): New expanded variable. 
 (LDFLAGS): Likewise. 	(COMPILE): Include CPPFLAGS. 	(CXXCOMPILE):
 Likewise. 	(LINK): Include LDFLAGS. 	(CXXLINK): Likewise. 
 (CXXLINK_SHRLIB): New. 	* config/open-axiom.m4
 (OPENAXIOM_HOST_DATA_PROPERTIES): Move 	ABI flags setting to
 OPENAXIOM_HOST_COMPILERS.  The CPPFLAGS and 	LDFLAGS instead of CFLAGS and
 CXXFLAGS.
