When changing CFLAGs on half the way...do I have to recompile my whole system? And -- only from the logical point of view -- redundancy may be not a sign of cleverness not a sign of cleverness but it does not hurt does not hurt the overall context since it instructs the compiler twice to do the same?! Bad compiler output is another thing. Keep hacking! mcc -- gentoo-user@gentoo.org mailing list
