Well, there are still valid reasons: if you *know* you'll run the binary only on non-mmx systems, you'd probably get rid of it to make the binary smaller and reduce possible points of errors. I'd consider the runtime-detection just as an extra failsafe check. > There are relatively few packages affected (<1%), so I think it's worth > a try.

Nobody forbids some packages having their own local useflags, if really necessary. cu -- --------------------------------------------------------------------- Enrico Weigelt == metux IT service - http://www.metux.de/ --------------------------------------------------------------------- Please visit the OpenSource QM Taskforce: http://wiki.metux.de/public/OpenSource_QM_Taskforce Patches / Fixes for a lot dozens of packages in dozens of versions: http://patches.metux.de/ --------------------------------------------------------------------- -- gentoo-dev@gentoo.org mailing list
