Thanks for updating this comment while at it :)

Previously we required `!LONG_IS_64BIT`, because the test would have
succeeded on platforms where it is 64 bit wide. But now that this test
works on all platforms I rather wonder whether we should completely drop
that prerequisite here, as we expect it to pass regardless of whether or
not long is 64 bit now.
