Re: Bignum not detected by default

I'm not sure about including it directly in the tarball but there are other situations too where it would be good to be able to use a library that can't be assumed to be part of the user's default configuration. The recent Carbon port comes to mind, but Windows might be another one. Instead of including the source, why not designate a directory in the source tree (say third_party) in which any source trees found therein are build and installed with the same paths as XEmacs. That would make a stand-alone install tree that would also allow the user to mix and match XEmacs and library versions (which is what pretty much happens already with the installed libraries).

An i386-optimized GNU MP Jerry> performs terribly on a Pentium 4, for example. It's not autodetected by GNU MP's configure? If not then our configure knows the CPU type pretty early in the piece so there is no reason why it can't pass it along when doing the GNU MP configure and build.
