The existing 32 bit architectures override these define to 32 bit in arch posix_types.h. There is request to support 64 bit time_t for new architecture [1]. According to the previous discussion we had (in [2]), defining suseconds_t as 64-bit, while probably reasonable for LP64 or LP64+ILP32 architectures, but can makes things troublesome for ILP32 architectures, not to mention the additional overhead. This series is compiled tested on ARM, mips, powerpc32 and x86_64, but only boot tested on ARM.
