Thanks guys... I think i'll just avoid variable length arrays for now until
I master gcc.
Ceasar: the value iBalance changes between the declaration and the code
snipet I gave. In this particular case iBalance is 2.
It makes much more sense to use vectors so I think I'll start using them.
Who knows maybe I'll end up switching compilers again, least my code will be
portable :)
Thanks again for the help!
