That is close, but the method forwarded to may or may not be virtual. I
don't know how the gnu gcc signatures worked, I have only heard second-hand
that it was a similar technique. There is an article at which explains how
the technique works using double-width pointers. There was also an article
on it, in the September 2004 issue of the C/C++ Users Journal.
