I think it did actually work, because unsigned is 32-bit on all the
relevant 64-bit systems.  unsigned long is 64-bit.

Yes.  There are Emacs configurations for both byte sexes of MIPS, for
instance, but I doubt a given OS would run both ways round, and it
seems highly unlikely it could be a runtime issue for a given binary.
For what it's worth, at least PowerPC, (some) SPARC, ARM, SH and
Itanic can also be BE or LE (e.g. the GCC submodel options).
