I wouldn't be so confident, if I were you :). Did you use *any* external
libraries in your project? You'll probably find that no distibution
actually ships the versions you used. Did you have any
implemenetation-defined behavior in your project? That behavior may well
have changed with a more up-to-date compiler -- and good luck getting
that old compiler running on any current platform. (&c.)

It would be interesting as a data point if you could just try a few
projects.
