[FFmpeg-devel] CDQ vs. CLTD

I just found out that gcc (actually, binutils) seems to support "cltd"
instead of of "cdq", and Sun C (as of SunStudio 12) supports only the former.
Since at least the AMD manuals do not have cltd but only cdq I am
reluctant to suggest changing it, but I'm still interesting if you have
any comments on this or suggestions.
In addition to this, only mathops.h and three other asm blocks seem to
hinder compilation with Sun C after --disable-mmx
