"exit" etc. improperly visible

[Nathan Myers]

(Apologies to those who have seen this before.  I can't
find where I posted it.)

Egcs-1.1 and recent snapshots treat some names specially,
and wrong.  In the example below, only std::exit is visible.

Incidentally, overload candidates would be most-usefully
reported with their enclosing namespace prepended.
