I suspect we're not referring to the same thread of context; I made the
comment in response to: http://gcc.gnu.org/ml/gcc/2005-01/msg00084.html
which I didn't interpret as referring to the portability of the compiler,
but rather code compiled by it having potentially different semantics as
a function of the "target's" type-sizes, potentially leading to the
non-portability of code between 32/non-32 bit int targets, which wouldn't
be a good thing, nor should be disregarded by presuming small non-32 bit
int targets are relatively insignificant; however if I misunderstood the
context, I do apologize for my then confusing response.
