It's supposed to be ABI-compatible on 32-bit, since all these types are 32-bit integers there, yes. (But maybe I messed up, do check!) But it may break source-level compatibility (if you only apply the Mach change but not glibc, or vice versa); as in maybe GCC will complain about int vs long in function prototype vs definition. I haven't actually checked, since I have both changes applied locally. Sergey
