Add a new shell variable in configure.ac extra_mpfr_configure_args. Set it to what you want to pass to the mpfr configure. Call AC_SUBST(extra_mpfr_configure_args). In Makefile.in add a line EXTRA_MPFR_CONFIGURE_ARGS = @extra_mpfr_configure_a...@. In Makefile.def change the host_modules entry for module=mpfr to replace --with-gmp-build=$$r/$(HOST_SUBDIR)/gmp with $(EXTRA_MPFR_CONFIGURE_ARGS). Run autoconf and autogen. Easy as cake. Ian
