  anyway, I have submitted a bug report 
  (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39435). We will see what the
  GCC developers say about it, maybe they will exhibit a simple GMP program
  showing the bug?
  
  Note that if I remove either one of -mpowerpc64, -Wa,-mppc64, or -mcpu=970,
  the compilation succeeds.
  
We needed -Wa,-mppc64 on some platform in the past, since a version of
gcc didn't pass the right options to the assembler.  Now, with the
present installation, it seems to do more harm than good.
