6 I think gcc-3.4* is still marked ~x86; however since that version -mcpu
7 has been depreciated in favor for -mtune.

9 As for the mmx information, that's valid across all gcc versions. If you
10 specify -march=pentium4 and -mcpu=pentium4 as part of your CFLAGS, -mmmx
11 and -msse, etc., will be implied by the compiler, and any programs built
12 to take advantage of the extensions will be able to do so.
