Lattice does do some common subexpression merging.  The compiler even does 
some simple cases without the optimizer turned on.

Your list of features looked a lot like a feature list for Lattice 5.0,
with a few exceptions.  It sounds like Lattice may still have an edge
in optimization (or maybe not).  Lattice isn't ANSI compliant in a few
places, so Manx may have an edge there.  Manx probably still has a big
advantage in compile time.  If Manx 5.0 is reasonably bug free, I'd
give them a small edge in the compiler wars, but it's pretty close.
Isn't competition wonderful?
