gmp-5.0.0 fails to build when configure option --enable-fat is being used

[Andris Pavenis]

Noticed that gmp-5.0.0 build fails if configure option --enable-fat has been specified.

It failed in the same way for the following targets in the same way I tested:

- core2-pc-linux-gnu (Fedora 12, x86_64) : the only specified configuration option: --enable-fat

- core2-pc-linux-gnu (CentOS 5.4 i386 in chroot under Fedora 12, x86_64): the only specified 
configuration option: --enable-fat

- i586-pc-msdosdjgpp (DJGPP v204pre) : some more configuration options used. For it I initially 
noticed the problem. Extra config. options perhaps does not matter as one can more easily reproduce
problem in Linux.

gmp-5.0.0 builds OK for me under Fedora 12 x86_64 if no configuration options are specified.
