Yes, although I think part of the intent was to support a system with 
individual arenas limited to 2**32 bytes even on 64-bit platforms, if 
nobody needs this capability the code would be simpler without it and 
removing it would fix the problem I mentioned. (Another part of the 
intent was to support pre-C89 platforms where size_t was a signed type, 
but that long ago became unimportant.)
