# APPLE LOCAL file build machinery
# Apple GCC Compiler Makefile for use by buildit.  
#
# This makefile is intended only for use with B&I buildit. For "normal"
# builds use the conventional FSF top-level makefile.
#
# You can specify TARGETS=ppc (or i386) on the buildit command line to 
# limit the build to just one target.  The default is for ppc and i386. 
# The compiler targetted at this host gets built anyway, but not installed
# unless it's listed in TARGETS.

# Include the set of standard Apple makefile definitions.
