   2 # Apple GCC Compiler Makefile for use by buildit.

   4 # This makefile is intended only for use with B&I buildit. For "normal"
   5 # builds use the conventional FSF top-level makefile.
   6 #
   7 # You can specify TARGETS=ppc (or i386) on the buildit command line to
   8 # limit the build to just one target.  The default is for ppc and i386.
   9 # The compiler targetted at this host gets built anyway, but not installed
  10 # unless it's listed in TARGETS.
  11
  12 # The following default target is for the benefit of those who try to
  13 # build llvm-gcc in the source directory.  GNU make will prefer to use
  14 # this GNUmakefile instead of the Makefile generated by configure.  Since
  15 # buildit always invokes this makefile with an explicit target, report an
  16 # error for the default target and some other common gcc targets.
