which GCC version old or new?

[Goodwin, Kevin M.]

Hello GCC Team,
    I am currently working on a new project here at SPAWARS system center
S.D. and we will be using RH Linux 7.1 or 7.2. 
as our development platform. The code will be entirely ANSI C with RH GLADE
as a GUI. We are trying decide on which 
version of GCC to use. I have heard some talk about binary incompatibility
with gcc 2.96. Will GCC 3.0.1 or 3.0.3 be our 
best bet?
    Any advice would be greatly appreciated,
    Sincerely,
    Kevin Goodwin   <kgoodwin@spawar.navy.mil>
