That sounds like pcc is lying. It is claiming to be gcc, then not supporting gcc extensions. Is there any easy way to identify pcc at compile time, such as a preprocessor macro it sets differently than gcc? > ../lib/wchar.h, line 34: warning: gcc pragma unsupported > ../lib/sys/types.h, line 24: warning: gcc pragma unsupported > ../lib/time.h, line 24: warning: gcc pragma unsupported > ../lib/time.h, line 24: warning: gcc pragma unsupported > ./stdio.h, line 1031: warning: unsupported attribute '__warning__' > ../lib/stdlib.h, line 21: warning: gcc pragma unsupported > ../lib/sys/types.h, line 24: warning: gcc pragma unsupported > test-float.c, line 374: unknown structure/union/enum > make[4]: *** [test-float.o] Error 1 Warnings like this, and the error in test-float.c, mean that all other packages using the same gnulib modules will have the same problem. We should fix it upstream in gnulib. -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
