Hi!

declaration:
void CopyTree(Vertex*& copy, const Vertex* originalTree)
throw(bad_alloc); [snip]
i get the following warning: warning C4290: C++ exception
specification ignored except to indicate a function is not
__declspec(nothrow)

It is just that msvc doesn't support exception specifications at all.
You could as well delete the "throw(bad_alloc)" part from your declaration.

Actually: it does support "throw()" which is actually quite important.
But MSVC recognizes nothing in between, that means it supports only no
throw and throw anything.
