about main must return "int"

[Amy Lin]

Hi, I am new with this list, and I need your help.

After installing Redhat 8.0 which has gcc 3.2, I ran into a problem when 
recompiling a project. with c++.  It errors out on "main" must return 
"int".  All my old codes with "void" main.  I used c++ from egcs-1.1-2 
(redhat 7.3) and it was no problem there.  My question is: Is this a bug 
of gcc 3.2, or this is a permanent change and I will have to change my 
codes?

Thank you very much.
