fix for xfixes cursor in amd64 (and any arch
with sizeof(long)!=4). Xfixes.h declares the pixels as a list of unsigned long
instead of CARD32 that is used on the serverside , resulting in 4 byte padding on amd64,
where sizeof(long)==8.This was breaking the XFIXES_POINTER_TO_YUV macro, but is now corrected.
