Hmm... After studying the spec a bit more, i think this is probably
correct. I therefore withdraw my patch.
(It still strikes me as somewhat surprising behavior, as i generally
wouldn't expect changing whether a function is inline or not to change
the behavior of a program, unless you're doing something like comparing
function pointers. And it's a little annoying that of the four or so
compilers i tested when trying to decide whether to rely on this,
all of them apparently got it wrong.)
