Well, I just tried old-flex.  Annoyingly, it has a package conflict with
regular flex, so it un-unstalled the modern one.  I'm definitely going
to install my own copy of flex 2.5.4a as a seperate executable, because
I don't want to use old-flex as the system default.

Maybe just make flex 2.5.4a part of the cross environment, so as not to
conflict with a modern version of flex.  

Anyway, I now am getting breakage with AMlexer.l.  I did do a 'make clean'
first.  Here's that error:

I had to stick in a 'using namespace std;' in all flex files.  Patch
attached.

At any rate, that was the last problem.  I've got a bitcc executable
now.  We'll see what happens next.
