uintptr_t doesn't guarantee what we need either. It only guarantees void* -> intptr_t -> void* conversion, but we also need 'intptr_t -> void* -> intptr_t'. The man page (stdint.h) doesn't say that intptr_t has to be the same width as pointers. It could be 128bits and gcc would still throw a warning. But if that's considered a non-issue, I'll change the code. tom _______________________________________________ xorg mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/xorg
