om

You may recall that I noticed that the compiler was emitting  "i += 1" 
instead of "i++" in
for loops and elsewhere.

When I turned my attention from the interpreter (which I consider mostly 
complete at this time, anyone wanting to test/synch up with my changes, 
now would be a good time), I started looking for anomolies in the C code 
and then at the compiler to see what caused them.

The compiler _WAS_ coded to emit "#to:do:" as ++ _HOWEVER_, the 
*smalltalk* compiler sees #to:do: as a *macro* which is automatically 
translated to #to:by:do: with an increment of 1.

Having discovered this, I edited the C compiler code for #to:by:do: to 
detect a value of +/-1 and emit ++ or -- accordingly.

My binary is now about 16 bytes shorter so it did do some good! =))))

The GC problem I mentioned earlier seems to have been caused by my 
attempt to do bitwise manipulations on word-variables. The mechanism 
behind this is far from clear.
