Configuration error when building libs

[Ctalk Project]

Greetings -

I encountered this error when configuring mpfr 2.4.2 against gmp  
5.0.1.  It doesn't interfere with the build, but it seems confusing.   
Here is the relevant portion of mpfr's config.log:

configure:20217: checking for gmp internal files

It appears that gmp does not install gmp-impl.h and longlong.h in  
<prefix>/include with the default configuation options.  Perhaps this  
example should also not be a default check unless linking against gmp  
sources explicitly.

The mpfr library still builds, as does libmpc and gcc, provided the  
compiler's build can locate the correct versions of everything else.   
No need to send a corrected version.

Thanks again,

Robert
