And you still haven't.  I asked a specific question above.  What is
your answer?  Would you use a "%u" format to print a value that's
defined with type unsigned long?  I inferred from what you wrote
that your answer would be yes.  If your answer is no, I'll gladly
accept that.  (And if so, what you wrote previously was unclear,
but I'm not going to worry about that if you clarify what you meant)

You've previously indicated that you find "%lu" uglier than "%u",
and that that's relevant to which one you would use.  Do you still
think so?

I would appreciate direct yes or no answers to both of those
questions.

So you'd write code that happens to work on some implementations rather
than code that's correct on all implementations.

You know that unsigned long is at least 32 bits wide, and therefore that
converting a uint32_t value to unsigned long will not lose information,
and therefore that

    uint32_t x = 42;
    printf("%lu\n", (unsigned long)x);

will work correctly.  You can do this without using the ugly
<inttypes.h> macros.  Why wouldn't you?

Sure, you can write code that happens to work on the only implementation
you care about, but in my opinion, aside from being dangerous, it's just
too much work.  I don't care whether uint32_t is defined as unsigned int
or unsigned long on a particular implementation, and I don't have to care.
