8 I don't really recommend that. A few things may have compile errors if
9 you globally use -mmmx, -msse, and -msse2. Instead, I suggest you set
10 the mmx and sse USE flags, and let portage add those CFLAGS for those
11 packages where it actually makes a difference and is supported.

13 Also, don't forget -fomit-frame-pointer and -pipe.
