Sorry for the late reply, I've been trying to finish a presentation.

I guess the problem from an autoconf standpoint is it's compiler
dependent and even file dependent. In this case the filename is
conftest_ipa8_conftest.oo. The lastpart is the name of the output
executable (conftest). The 8 is the length of the executable filename.
The extension .oo is the optimized object file so that linking *.o
wouldn't pull in the ipo optimized objects.

I don't get any problems with the intel compiler as it just creates
temporary objects, so I would just consider this an oddball PGI thing.
