# ATTENTION: This version of the makefile only works with gmake.
#            This Makefile not only generates object files, but also additional
#            files needed during compilation:
#                nativetypes.hh
#                nativetables.hh
#            All object files and the *.hh can be deleted savely. They will be
#            generated automatically.
