  It seems you are correct.  I wanted to build a completely standalone
  version of gcc-4.9 to test, so I used the
  /src/contrib/download-prerequisites script located in the gcc source. 
  It appears to be version 4.3.2 as can be seen from the wget link inside
  that script
  (ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2).  Before I
  provide a more thorough bug report, I'll try an updated version of gmp. 
  However, I feel that if gcc-4.9 provides that link in the source, it
  should build as expected.  Do you recommend filing a report to update
  the link/ broken build with those sources?
At least the gcc folks might want to know that their new compiler and
the obsolete GMP they suggest do now work together.

But if you report it to them, you cannot just say that it breaks on an
undefined machine with undefined versions of involved programs.  Just
like us, they'll need all relevant information.

(My tea leaves suggest that this is indeed a gcc bug.)
