I applied that patch this morning and sure enough, it does fix the 
problem.  Thanks to Andrea for noticing it.

BTW...  while reading the patch I noticed that, quite by accident, the 
source file 'pixman-mmx.c' had somehow gotten excluded from my MSVC 
build project, so I took the opportunity to add it.  Although the build 
still succeeds, I see several warnings of this form while building 
'pixman-mmx.c':-

       pixman-mmx.c(586) : warning C4799: function 'whatever' has no 
EMMS instruction

I don't know if that means anything bad but I thought it wouldn't do any 
harm flag it up.  Here's a list of the affected functions:-

       function 'expand_4xpacked565' has no EMMS instruction
       function 'is_opaque' has no EMMS instruction
       function 'is_equal' has no EMMS instruction
       function 'to_uint64' has no EMMS instruction
       function 'expand_4x565' has no EMMS instruction
       function 'is_zero' has no EMMS instruction
       function 'store8888' has no EMMS instruction
       function 
'fast_composite_scaled_bilinear_mmx_8888_8_8888_none_OVER' has no EMMS 
instruction
       function 
'fast_composite_scaled_bilinear_mmx_8888_8_8888_pad_OVER' has no EMMS 
instruction

I've no idea what it means but I hope that's useful.
