The standard explicitly says (N1570 7.21.6.1p9):

    If any argument is not the correct type for the corresponding
    conversion specification, the behavior is undefined.

There might be some amiguity about what "the correct type" means.  A
conforming compiler could recognize something like `printf("%u\n", 42)`
as incorrect and issue a warning, or in principle even reject it.

On the other hand, a non-normative footnote in 6.2.5p9, discussing the
representation of corresponding signed and unsigned types, says:

    The same representation and alignment requirements are meant
    to imply interchangeability as arguments to functions, return
    values from functions, and members of unions.

It will almost certainly work, as long as the value is within the range
of both types, but there is *no* good reason to depend on that.  Just
use the correct format.

My preference (assuming I can't depend on support for "%zu") is to cast
to unsigned long and use "%lu", even if I happen to know that the value
is small.  It saves me the trouble of thinking about what the value is
going to be.  The advantage of `printf("%d\n", (int)sizeof foo)` over
`printf("%lu\n", (unsigned long)sizeof foo)` is minimal, and in my
opinion is overridden by the advantage of consistency.

Note that it's theoretically possible that "%lu" could print an
incorrect value, but only if the size being printed exceeds ULONG_MAX,
which is at least 2**31-1.  That can only happen if size_t is wider than
unsigned long long; I know of no existing implementation where that's
the case.
