To get the failure you need not to have GMP installed somewhere the bootstrap compiler would otherwise find (e.g. uninstall your system GMP package before testing). The failure is building stage 1. > I am actually not totally sure how to respect the -with-gmp argument > in libcc1. auto* tools are not my strongest skill. ;) > > I notice gcc/configure.ac I think just exports the variables to > Makefile.in from the main configure script.

I think you should (a) copy AC_ARG_VAR(GMPINC,[How to find GMP include files]) from gcc/configure.ac; (b) copy GMPINC = @GMPINC@ from gcc/Makefile.in; (c) add $(GMPINC) to AM_CPPFLAGS. -- Joseph S.
