forgotten. I hope I got the dates right (timezone issues).

Simplify def handling, use far data.
...
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.
Also, start using far data for ObjQC structures.
The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.

Get qfcc running again.
...
It segs when it tries to link, but that's because a real object file has
not been created yet. However, I can get my tree and flow diagrams :)

Use function pointer tables instead of switch.

This seems to be better for complicated code. switch seems to be better
suited for relatively simple code.

Nuke bind expressions.
...
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).

Link a bool to its block rather than the block's head.

Print expressions as dot files.

Add QuatInverse to calculate 1/q.
...
There's still no direct quaternion division because I don't know if the
definition of q1/q2 is (1/q2)*q1 or q1*(1/q2) (it does make a difference).

Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage.
...
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.
emit.c has been gutted in the spirit of "throw one away".
There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.
