Bootstrapping with an in-tree copy of mpfr (version 2.4.1) and using an installed gmp in a directory specified by --with-gmp=foo yields an error when the bootstrap process gets to configuring the mpfr dir:
> configure: error: Do not use --with-gmp-build and other --with-gmp options simultaneously. > See `config.log' for more details. > make[1]: *** [configure-mpfr] Error 1 Older versions of mpfr built in-tree are more forgiving and mask the issue but the bug is merely latent in those cases. The problem is that the top-level configure process assumes that if one is building mpfr in-tree then gmp is also being built in-tree and therefore the second --with-gmp* flag is specified pointing to the a gmp build dir which does not exist in this scenario.
