Hey ya, I have just built from a few spec files using gcc4 (/usr/gnu from spec-files-extra), and it did not like "-fno-omit-frame-pointers". I had a look in both the gcc v3 and v4 manual pages, which say that it should actually be "-fno-omit-frame-pointer". We probably need to fix this in spec-files, spec-files-extra, spec-files-xfce etc... Doug
