Jan Nieuwenhuizen 25c29ecb6d core: Integrate garbage collector/jam scraper. 
* mes.c (r0, r1, r2, r3, stack):  New globals.
  (gc_loop): Handle MACRO and SCM.
  (gc_copy): Handle FUNCTION, allow for pre-allocated SCM and SYMBOL.
  (assq): Flag any BROKEN_HEARTs.
  (vm_call): New function.  Enables moving C stack to GC stack.
  (evlis_env, apply_env, eval_env, expand_macro_env, begin_env,
  if_env): Use vm_call-indirection.
  (call_lambda): New function.
  (vm_apply_env): Rename from apply_env.  Remove parameters, instead
  use r1, r2 and r0.
  (vm_evlis_env, vm_eval_env, vm_expand_macro_env, vm_begin_env,
  vm_if_env): Likewise.
  (acons): New function.
  (mes_environment) [!MES_FULL, MES_MINI]: Add cpp switches to create minimally
  filled environment, for debugging.
  (main): Print free value at exit.
* define.c (define_env): Use vm_call-indirection.
  (vm_define_env): Rename from define_env.
* quasiquote.c (eval_quasiquote): Use vm_call-indirection.
  (vm_eval_quasiquote): Rename from eval_quasiquote.
* tests/gc-2.test: New test.
  tests/gc-2a.test: New test.
  tests/gc-3.test: New test.

Mes -- Maxwell Equations of Software

Mes aims to create an entirely source-based bootstrapping path.  The
target is to [have GuixSD] boostrap from a minimal, easily inspectable
binary --that should be readable as source-- into something close to
R6RS Scheme.

As bootstrapping is presumably easiest and probably most fun with
Scheme, the next step for Mes is mescc: a C compiler/linker to
boostrap into GNU Gcc and GNU Guile, possibly via Tiny-CC.

Mes is inspired by The Maxwell Equations of Software: [[http://www.softwarepreservation.org/projects/LISP/book/LISP%25201.5%2520Programmers%2520Manual.pdf][LISP-1.5]] -- John
McCarthy page 13.

Mes is free software, it is distributed unde the terms of the GNU
General Public Licence version 3 or later.  See the file COPYING.
