buildtools/autoconf/GNUmakefile

# Having a separate GNUmakefile lets me `include' the dynamically
# generated rules created via Makefile.maint as well as Makefile.maint itself.
# This makefile is used only if you run GNU Make.
# It is necessary if you want to build targets usually of interest
# only to the maintainer.
