It's going to be very difficult to compile such old code on a modern system. You will need a lot of patience and persistence, and it is unlikely that people on this mailing list are going to want to give you the answer to every little problem along the way. You will probably need to proceed in several stages, building an old GCC with your existing compiler, then using that to build an older one, and using that to build an older one, until eventually you can compile egcs-1.1.2 You could try installing an old version of Debian or Ubuntu in a VM or a container, and compile egcs inside that VM/container. That might be a shortcut to getting an old environment (with old GCC and glibc) that can be used to build even older versions.
