Yes, and verify that GMP and MPFR are correctly compiled with "make check".  
Recent versions are miscompiled on SPARC/Solaris by GCC 4.3.x for x < 3 or 4.

The recommended versions (GMP 4.3.2, MPFR 2.4.2, MPC 0.8.1) also work fine if 
compiled by the latest GCC 4.3.x compilers (or compilers of later series).
