Okay, I figured out how to install multiple GCC's (astoundingly easy) 
and, more importantly, how to convince "make" to use them.

Interestingly, I have not managed a clean compile with any compiler 
version I tried.

The compilers marked "pass" below successfully compiled "sched.o", then 
later aborted with a message similar to:
