-----------------------------------
In the installation instruction , the writer recommend me use gcc2.95 to
compile but my gcc is gcc3.3.2. So I guess may be this is the problem
So any person help me to fix this. What is the reason?? How to uninstall
gcc3.3.2 and reinstall gcc2.95
Please help !!!!!
