That's a wee bit broken. And not just with my commit, but in general, there are other configure checks that test whether an option is supported or not, just grep configure.in for -Werror. > So probably configure should check if this warning is printed to > stderr when checking what command-line options are supported? That does not quite work, e.g. the message can be translated. But the bug seems to exists only with Clang < 3.1, so the problem can be worked around by checking for such versions and overriding all results of such checks to values manually found out. -- Lubos Lunak l.lu...@suse.cz _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
