> If you want a particular flag to be added to CFLAGS/CXXFLAGS within an ebuild, you can inherit flag-o-matic, then call "append-flags -fgnu89-inline" in src_configure before the econf line. If you explicitly only want to set CFLAGS (and not CXXFLAGS), then call "append-cflags" (there is also a append-cppflags, append-cxxflags, append-ldflags, append-fflags). -- Jonathan Callen
