GCC version compatible problem

[Lu Peng]

Dear gcc team,

I got some gcc version updating problem. I have some programs which
run well with gcc 2.96 (in RH 7.3) but always failed with gcc 3.2.2
(in RH 9.0). Does gcc have compatiblity to old versions? If so, could
you tell me what I should do?

thanks a lot,

Lu Peng
