I'm running from the 1.3a tarball, and winex doesn't use the cflags I defined.
it's not supposed to. have look in the ebuild itself, and you'll see a comment from the ebuild maintainer as to why. essentially things won't build right, if you don't use their cflags.
But, as you know... Linux kernel developers say the same about building the kernel with gcc3.1 for example. A lot of projects say that. We should ignore them, or at least have the option to do so. (USE=forceoptimize, a different ebuild for optimization... don't know... something).
