If you are running configure then you are trying to compile GCC from source.
You cannot install GCC from source without at least some kind of ISO C-90 compiler to hand. This is because
GCC is itself written in C
If you want to compile GCC from source, you really do need to read the instructions:
http://gcc.gnu.org/install/
I recommend installing one of the binary distributions of GCC. You can install it with a non-standard prefix, then using that to compile GCC. Or just stick with the binary.
