Re: [PATCH] uapi: Make __{u,s}64 match {u,}int64_t in userspace

Hi!

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
