When something similar happened when I was working on the OS for CCI's 6/32
I just said 'Ok!', hacked the compiler's table a little, left a compilation
running overnight, and the system was ready the next morning. (A little
exaggeration perhaps, but it did take less than a week).
But of course, our system was written in C...
