Thanks for the report. The test-intprops.c file comes from gnulib, so fixing it there will fix it for other packages that also inherit the same test. For our reference, can you please paste the actual source lines that the compiler is complaining about? Even better would be computing the preprocessed (but uncompiled) output, and showing the corresponding lines after macro expansion. That may help us figure out whether the bug is in the PGI compiler rather than our testsuite, and maybe even give us some ideas of ways to work around the problem (whether it be avoiding the compiler bug or fixing our code portability). > > I don't think test-intprops.c is compatible with the PGI compilers. Is there an easy way to access a machine with a PGI compiler, so that you don't have to do all the debugging yourself? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
