LP64 remains a good idea. Pity the ANSI C committee for C89 didn't have a spine.

(Yeah they had to navigate the 16->32 bit transition, but LP32 for 32-bit ANSI C
systems would have made OBVIOUS SENSE. "There are older systems that aren't
LP32" was a given. The 68k came out in 1980 and the 386 in 1985, they weren't
exactly taken by surprise by 32 bit registers and a flat memory model...)
