I don't really have any doubt that somebody, somewhere, wants to
override a function in a C++ shared library, and wants the overriding
function to throw an exception.  There is really only one correct
compiler behaviour here.

But if gcc 4.1.1 behaved one way with regard to overriding a function
with a function that throws an exception, I think we can probably get
away with having gcc 4.1.2 behave the same way.  It should ideally be
recorded as a known issue somewhere, though.
