Thanks for your reply.
My driver is failed at run time when it was compiled with gcc-2.96 under
RedHat7.X OS(it can be insmod but cannot work properly, but if I use
egcs-2.91 to compile, then it works fine).
So I think that if there is the egcs-2.91 & gcc-2.96 difference list, then
it will help me to save lots of time to update my device driver.
I am confused on this problem:-(. Any pointers will be great appreciated!

That's analogous to saying: I've lost something in your house, but I'm not
going to tell you what I lost. Instead, I want you to send me a complete
list of everything in your house, so I can see if the list contains what I
gcc "2.96" is a Red Hat release, it didn't come from the GCC project.
But even if it did, we couldn't help you with a request like that.
You give no information on what failure you see (compile time? run
time?). And C programs with undefined behavior (like access to
uninitialized variables) may accidentally work with one compiler version
and not with another, or break when optimization is turned on.
