Good idea.

Thank you very much for testing.

I've checked in the following, slightly different patch (the C++ and F77
drivers don't name-collide with `pentium gcc', those were named pg++ and
pg77 respectively), adding ChangeLog, THANKS and NEWS entries.

The patch below is against branch-2-0, the ones against HEAD and
branch-1-5 are analogously derived from Jeff's patches.

Cheers,
Ralf
