After the discover of some problems regarding gcc 3.4, -march=pentium4 and xorg-x11 there was the ide born of /etc/portage/package.cflag. The ide is to have a file were somehow the user could specify witch cflag should be added/removed from the one in make.conf for a specefic package. Right now if I do "emerge -e world" i have afterwards to emerge xorg with the -mno-sse2 flag to make it work efter restart. I want somehow to be able set this in a file. Here is the thread: http://forums.gentoo.org/viewtopic.php?p=1533539 (GCC3.4)
