  I recently started using gmp 4.2.1 in my GCC builds instead of 4.1.4.  I

  reference to __gmpn_umul_ppmm.  I don't have this problem on 32 bit
  hppa.  If I look at the 32 bit archive library, it has __gmpn_umul_ppmm.
  If I look at the 64 bit archive library, I have __gmpn_umul_ppmm_r, but
  no __gmpn_umul_ppmm.  Does anyone have any ideas about what might be
  going on?

Your report is too terse for us to understand what is the problem.

If you cannot build GCC, it sounds like a GCC problem, not a GMP
