Re: [RFC] asm-generic/{unistd,types,posix_types}.h for new arch

Actually, gcc does have the _LP64 and __SIZEOF_POINTER__ macros (as well 
as __CHAR_BIT__), although I don't know how far back it does have that. 
     If it has been with us for long enough it might be possible to 
switch over to using panarch macros.

Worst case the oldest compilers had <limits.h> and 
"#if ULONG_MAX == 0xffffffffUL", though I wouldn't like
myself to be using a setup where <limits.h> got pulled in.


Thanks,
