Is this indeed a bug?Sounds like a bug.
I just found something in the bug database relating to this: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19232 According to Andrew (#3) it doesnt eject a warning becuase the function isn't inlined. I'm not sure thats a valid reason for not ejecting the warning. Just becuase the function can be over-ridden in another TU doesn't mean that the one that is currently declared, and called with sign differnces, shouldn't eject a warning. Kean
