Wow. Very impressive. What a pity noone has thought of that earlier...
I have modified the current vintage implementation to use this form of
typeof, allowing it to compile with VC6.5 as well.

I guess this deprecates most of the vintage code, since that was
implemented in order to allow support of VC6.5 and VC7.0.

This actually makes it possible to properly implement remove_xxx for
VC6.5 and VC7.0 without any form of registration :)
