Since we started using gcc. Since we have a kernel that even on a CISC
machine is bigger than a 16-bit address space can encompass.
ANSI C has to cater to elevator controllers running on 8-bit micros.
NetBSD doesn't. Unless you _are_ writing for toasters or elevator
controllers (in which case you're probably not actually using C but
rather a mostly-C-like language tuned for your processor) I have no
hesitation in recommending that you code assuming ints are at least 32
bits. _I_ certainly have no hesitation about doing so.
On a more practical note, changing them to ints will fix the problem
for us, and for bitty boxes with 16-bit ints, while it won't fix it, it
will not make it any worse. When was the last time you saw Berkeley
mail running on a system with less-than-32-bit ints? On my NetBSD/sun3
machine, /usr/bin/mail is 73728 bytes. Stripped. Text alone is 65536
bytes - that doesn't leave room for the shim at address zero, even
assuming a 16-bit machine with code as compact as the 68k's.
