Hi Bruno,

FWIW, I had reported these issues too:

  http://thread.gmane.org/gmane.comp.lib.gmp.bugs/1979

I can't find the source repository (!) so I don't know whether a similar
patch was applied.

This would break with GCC < 4.2 because the `gnu_inline' attribute is
supported starting from GCC 4.2.

Thanks,
