[mythtv] Myth doesn't compile under FC3

[Chris Petersen]

Trying to compile myth under fc3, and I get the following error:

i386/dsputil_mmx.c: In function `h263_h_loop_filter_mmx':
i386/dsputil_mmx.c:634: error: can't find a register in class 
`GENERAL_REGS' while reloading `asm'

Googling reveals that some people on the atrpms list have had this 
problem.  It looks like things compile fine for athlon (which is fine 
for me until I decide to upgrade my main mythbox), but this could be a 
real problem for intel-cpu users.

My guess is that is has something to do with the new gcc's more strict 
C++ handling.

Anyway, a warning to prospective fc3 updaters, and a bug report for the 
devs.
