One more thing. What kind of MIPS ABI does this code use? The following wiki page suggests that there are many ABI variants: http://www.linux-mips.org/wiki/MIPSABIHistory If you are using o32 ABI in your code, then it probably also makes sense to check for _ABIO32 define? Or somehow make sure that pixman will not misbehave if used with some other ABI. -- Best regards, Siarhei Siamashka
