I could be persuaded otherwise with an example of a program for which changing __s64 from 'long long' to 'long' would break *binary* backward compatibility, or similarly for __u64.C++ could break.
Thinking of this again we can detect C++ as well so it can be safely enabled just for C with: #if !defined(__KERNEL__) && !defined(__cplusplus) && __BITSPERLONG == 64 # include <asm-generic/int-l64.h> #else # include <asm-generic/int-ll64.h> #endif -- Cyril Hrubis chrubis@suse.cz
