[Clfs-support] gmp-4.3.1. fails to compile in Ch. 5, "Constructing Cross Compile Tools"

[Dan McGhee]

Using SVN-20090831-Native-Multilib

Compile fails with "C++ compiler not available, see config.log for details."

This, I think, is the appropriate section of "configure:"

The archives talked about a situation with gmp and gcc last year before 
the stable release.  I tried the various switches and flags for gmp in 
Ch.6--with --prefix=/cross-tools.  The results were the same.

This is beyond my level of knowlege so I will appreciate and perform any 
suggestions and directions.

Thanks,

Dan
