C has been around for a long time and there is always a

to any sweeping generalisation that isn't backed-up by a standards
document.
BTW I was slightly wrong it is longs not int's that change depending on
word size:

Just remember this, char <= short <= int <= long. Anything else can be
anything. Saying that an int is always four bytes is like saying an
int is the same size as a pointer, both of which are assumptions that
are often taken but are very wrong. A lot of what decides the sizes of
ints is more compiler implementer than anything else. Depending on
your system, you'd want your 36 bit ints instead of being limited to
only 32.
But if you don't care about portability, then an int is always 32 bits
and it's always in little endian order.
