 У меня:
 `-mcpu=CPU-TYPE'
      Tune to CPU-TYPE everything applicable about the generated code,
      except for the ABI and the set of available instructions.  The
      choices for CPU-TYPE are `i386', `i486', `i586', `i686',
      `pentium', `pentium-mmx', `pentiumpro', `pentium2', `pentium3',
      `pentium4', `k6', `k6-2', `k6-3', `athlon', `athlon-tbird',
      `athlon-4', `athlon-xp' and `athlon-mp'.

 Смени gcc на 3.2.x должно заработать.
