[C++, RFA] correctly detect conflicts between function and using decls

[Alexandre Oliva]

A bug report was filed into Red Hat's bugzilla system (URL in the
testcase below) regarding an inconsistency in detecting and reporting
conflicts between function and using declarations.  We'd reject extern
"C" matching declarations should the function declaration appear after
the using declaration, but would accept them in reverse order.

Here's the patch, containing a testcase that covers all possibilities
I could think of.  Ok to install?
