You shouldn't have to upgrade GCC but it would indicate that you don't have it entirely installed. Must be some library packages missing. The configure script just creates a very small C program of a few lines and tries to compile it. If it can not then it gives that error message. Can you create your own little test program and try and compile it and see what errors gcc is really giving? Try putting this in a file called "tst.c":
Then compile it with "gcc tst.c" and see if it gives you an error. Also look at your "configure.log" to see what error messages it may have produced.
