gcc 4.1.2 is fairly old. Are you sure your version of gcc is too new,
and not too old?
gcc is normally backward compatible for standard programs, but it is not
always backward compatible for programs which use gcc extensions. Like
the Linux kernel. You will have to ask the kernel developers which
versions of gcc can compile the kernel version you care about.
