# 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.

# The following default target is for the benefit of those who try to
# build llvm-gcc in the source directory.  GNU make will prefer to use
# this GNUmakefile instead of the Makefile generated by configure.  Since
# buildit always invokes this makefile with an explicit target, report an
# error for the default target and some other common gcc targets.
