[boost] signals lib (C++ Builder patches)

I have some patches which get the signals lib working with C++ Builder 6
(see below), if there are no objections I'll check these in sometime soon.
As far as I can tell the changes affect only the implementation detail not
the interface, but they're fairly substantial, so I'd like approval before
going ahead with them.

Anyway here's the diff:
