--- Comment #5 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
We're talking about the sequence of pp-tokens in the expansion of bar(foo, 
addr), which is (foo) (addr), where foo is followed by ), not about the 
definition.

Please take any further questions on this to gcc-help; this question is 
not appropriate for Bugzilla since it does not involve a bug or any other 
kind of deficiency in GCC.
