--- 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.
