[cairo] pixman & win64

[Thomas Stover]

I hate to even bring this up, but I will anyway for any others in the 
same boat I am. Apparently  Visual Studio 9 x86_64 doesn't allow inline 
assembly. It must be placed in a separate file. This I discovered while 
trying to build pixman 0.12.0. From what I gather it will work if you 
put it in separate files. I'm also not sure that the _asm section it's 
error-ing out on should even be reached in my configuration. I'll keep 
trying some things, but maybe this is already fixed somehow?
