Unix equivalent of a variant??

[Jonathon McKitrick <jcm@xxxxxxxxxxxxxxxxx>]

Hey everyone,

I'm finally doing something very exciting here at work: porting software to
Unix!

I need the equivalent of a variant, however.  A hold-everything variable
that can be any type in C/C++.  Is there something already out there I can
use or should I just roll my own?
