I don't have a copy of gcc-3.2 set up at present to test with, can this wait 
until after the release?

Ummm, an aggregate has special meaning in the std, and it's *not* the same 
as "is_class_or_union"; an aggregate is a type that can be initialised with 
an initializer list:

MyAgg f = { a, b, c, };

There's also no way to implement it as far as I know, not that that's 
stopped us before mind you ;-)
