at the end of AC_LINK_IFELSE (formerly AC_TRY_LINK), the generated
files are deleted. What is the name of the filei(s) with IPA
information? Perhaps it should be deleted, too.
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.
Have a nice day,
