warning... the last patch "pixman_OPT_MMX_pu_mulhi_pu16.patch" is 
missing something... the inclusion of "xmmintrin.h" somewhere at the top 
of pixman-mmx.c.
I sent the patch that way to bring you attention on my last question 
about whether or not including "xmmintrin.h" as part of USE_MMX should 
be considered an awful idea or not ;-)
