I'm not sure I'd go as far as saying "has never been a problem".  It's
"mostly worked", but did have optimization losses and various minor
issues from time to time.  There was enough of a problem that (before
the days when we switched to HOST_WIDE_INT being "long long") I wanted
to be sure that I used a 64-bit host since I needed to build 64-bit
targets.
