In theory, yes it is sort of obsolete - sse and sse2 are the preferred |
7 |
method. However, so long as you have specified -march=pentium4 (and |
8 |
-mcpu=pentium4 or -mtune=pentium4 with >=gcc-3.4) mmx/sse/sse2 will be |

implied as part of the compilation process. |

As for mplayer - unless you set the appropriate use flag, then almost |
12 |
all C(XX)FLAGS will be remove from the process as (like gaim) it is |
13 |
notoriously flaky with anything other than the basic settings. |
