Yes, the 3rd example worked - but then so did taking it all out altogther.
I've been having various linking problems all day as I try and combine c and
cpp modules with global variables and such, and can only think that various
use of extern "C" { and such have been causing problems.

So for now, I don't seem to explicilty mention stdc++ at all and it all
links fine

I'll get back if I discover something else.

THanks

Sam
