	Thanks for your response. I looked at config.log and I got the 
following information about sbrk. This error only occurs when I type 
"make." If I reconfigured the build directory and typed "make -j8" (or 
whatever the number of cores I have on my machine) it seem to build 
fine.

A race condition? Or the first make created stuff that the second try 
picked up?

configure:10333: checking whether sbrk is declared
| #ifndef sbrk
| char *(*pfn) = (char *(*)) sbrk ;

The result of grep is not so useful, what's nearby would help more. You 
should probably file a bug report and include the whole gcc/config.log 
file.

(H.J. Lu noticed another gmp.h issue, but that's only for in-tree gmp and 
you seem to have an external one)
