I don't see the flag handling in the ebuild actually, you can commit it. 3.14159@gmx.net 2004-10-11 11:55:10 0000 i still have this problem,the ebuild also has no replace-flags.... mattam@gentoo.org 2004-10-11 13:43:54 0000 It should have, i'll add it tomorrow, in the mean time you can build with CFLAGS="". mattam@gentoo.org 2004-10-12 12:37:39 0000 I added strip-flags which removes -O3 and other quite untested flags. carsten@tschense.net 2004-10-20 10:07:29 0000 "strip-flags" doesn't remove -O3. Still the same ;) Use "replace-flags -O? -O2" mattam@gentoo.org 2004-10-20 11:04:20 0000 I fixed that in CVS, now closing the bug :)
