vector.tcc:452: error: expected unqualified-id before ‘(’ token

I wasted so much time to solve this problem, while compiling code in c++ in fedora 8.
Now I found out the problem. The problem was due to the not linking c++ in old version of gcc, as I installed older version of gcc.
Oh, god!! finally I found out the problem. I searched 2 days for the solution on the net.
