I actually don't think it's a bug. The error message is associated
with the function declaration symbol, so it actually makes sense that
there can be only one error message per callee - not per caller.

Using "__LINE__" to then create fairly unique symbols (modulo
#include, of course) gets around it in a pretty natural way as ddaney
said, so if we care enough.  I don't think it's a big issue (as
mentioned, I'd worry more about us making sure it's reliable enough to
be used - we've had gcc sometimes fail to compile things out just
because some optimization was not working well enough).
