mythtv fails at libavcodec (in distclean state)

[Wylie Swanson <wylie.swanson@…>]

I suspect it may be related to ​dsputil_mmx recent changes

Creating libs/libmyth/mythconfig.h and libs/libmyth/mythconfig.mak

WARNING: When using --enable-proc-opt you must include the

output of ./configure along with any bug report.

libs/libmyth/mythconfig.h is unchanged

I can confirm this bug on Slackware-current, with kernel 2.6.15.6 on an Athlon thunderbird 1.4GHz, gcc 3.4.6, and configure flags --enable-opengl-vsync --enable-xvmc.

I started noticing it with svn 9483.
