Right. I understand why it doesn't compile and how to work around it (with gcc
at least). What I'm still not convinced of is that it's not a strict conformance
bug. The same point was raised in the discussion you pointed me to but I
couldn't find where it was addressed or if it was communicated to WG14. I.e.,
even if the requirement in C99  (that makes the test case well-formed) is
non-normative and bogus, strictly speaking this would still be a conformance bug
in the gcc implementation of va_list (after all, it is a gcc builtin, so it
seems that the compiler could do some magic whereby taking the address of a
va_list declared as an argument to a function would produce va_list* and not
va_list**).

Do you happen to know whether there's a C99 issue to fix the footnote?
