2002.10.03 ~03  Compiling Scheme to Q3VM bytecode

Right now, compiling Scheme directly to a Q3VM file is possible.  The
opcodes for Q3VM are all laid out, the peculiarities of Q3VM are in the
q3lcc patch, the memory structure is not complex.  A suitable halfway hack
is to compile for a SECD machine, then translate the SECD operations into
Q3VM opcodes.  The SECD layer could be done away with entirely, but that's
an entire research project in of itself ("Optimized Scheme Compiler for
Quake 3 Virtual Machine").

Programs for compiling Scheme into SECD byteocde are already available, and
written in... Scheme.  Well, C compilers are written in C, so that's not so
entirely weird :)

I'm wondering if it may be more worthwhile to try to hack one of the
existing Common Lisp compilers to target Q3VM, instead of trying to
compile Scheme via SECD.
