Well, every time I run it, it claims to be based on V1.1a.  Unless the 
cfront program is lying to me, that would be pretty conclusive, eh?

What they left out was documentation on the V4.x compiler, because they
obviously don't intend to support the use of the C compiler as part of the
C++ distribution.  Like, when/if the single phase compiler is written, the
LC1 program, at least, disappears from the Lattice distribution.

Absolutely.  The cfront program also needs a very large stack, I usually
give it 1/2 a meg or so.  It'll run with a much smaller one, but it tends
to crash much more.
