(we might also determine that such systems require an ISO-C compiler

is present.)

This seems like a poor argument. The availibility and suitability of
modern GCC for building GDB does not imply that modern GCC will be
suitable for building the application to be debugged.

For the systems of concern here they have old compilers, and equally old shipped debuggers. While a current GDB might work in theory, in reality it just isn't worth the effort of finding out - remember step-1 is somehow build/test an ISO-C compiler.
