* configure.in: Require GMP-4.1+ and MPFR-2.2+. Don't check
need_gmp anymore.
I'm getting
configure: error: Building GCC requires GMP 4.1+ and MPFR 2.2+. Try
the --with-gmp and/or --with-mpfr options.
1. Is this intentional? 2. Is it supposed to apply to the host, the target, or both?3. If it's intentional, what is the list of platforms that you intended to prevent building, that is, platforms which GCC used to support but on which GMP or MPFR does not build?
4. Are you aware that the GMP home page says[2006-05-04] GMP does not build on MacInteltosh machines. No fix planned for GMP 4.x.
and indeed it does not appear to build correctly when configured on my MacBook Pro?
5. Are you aware that the GMP home page saysNote that we chose not to work around all new GCC bugs in this release. Never forget to do make check after building the library to make likely it was not miscompiled!
and therefore this library needs to be part of the bootstrap, not built separately?
6. The regression tester does actually have GMP installed, but it is, not in /usr/local. Should this code be searching for GMP and mpfr in more places if it is not found?
Because of the severe nature of this problem (everything doesn't build, multiple hosts affected), I'd like you to consider backing out this patch until the problems are fixed. I'll work on a patch which just disables the check for Darwin.
