Jan Nieuwenhuizen c3fdfedb20 mes: resurrect full reader in C core. 
* module/mes/read-0.mes (defined?): New function.

  read-line-comment, read-list, read-character, read-hex, read-octal,
  reader:read-string, lookup, read-hash, read-word): Only define if
  not %c-reader.
* module/mes/base-0.mes (defined?): Remove.
* src/mes.c[MES_C_READER]: Set ARENA_SIZE=10000000.
  (scm_symbol_quasiquote scm_symbol_unquote,
  scm_symbol_unquote_splicing, scm_symbol_syntax,
  scm_symbol_quasisyntax, scm_symbol_unsyntax,
  scm_symbol_unsyntax_splicing): New symbol.
  (scm_symbol_c_reader): New symbol.
  (MAKE_KEYWORD)[MES_C_READER]: New define.
  (mes_symbols): Define %c_reader.
* src/reader.c (read_word_)[MES_C_READER]: Extend to full Scheme
  reader.

Mes -- Maxwell Equations of Software

[[https://gitlab.com/janneke/mes][Mes]] aims to create full source bootstrapping for [[https://www.gnu.org/software/guix][GuixSD]] as part of the
[[http://bootstrappable.org][bootstrappable builds]] effort.

It currently consists of a mutual self-hosting [close to Guile-]
Scheme interpreter prototype in C and a Nyacc-based C compiler in
[Guile] Scheme.  This C prototype will be rewritten in [[https://github.com/oriansj/stage0][stage0]] M1
assembly (or possibly stage2 slow-LISP, or ...).

The Scheme interpreter prototype (mes.c) has a Garbage Collector, a
library of loadable Scheme modules-- notably Dominique Boucher's [[https://github.com/schemeway/lalr-scm][LALR]],
Pre-R6RS [[https://www.cs.indiana.edu/chezscheme/syntax-case/old-psyntax.html][portable syntax-case]] with R7RS ellipsis, Matt Wette's [[https://www.nongnu.org/nyacc][Nyacc]],
Guile's [[https://www.gnu.org/software/guile/docs/master/guile.html/PEG-Parsing.html][PEG]] --and test suite just barely enough to support a simple
REPL (repl.mes) and simple C-compiler MesCC (mescc.mes).

MesCC can compile a [[https://gitlab.com/janneke/tinycc][modified TinyCC]] that is close to being
self-hosting.  A GNU Ccc-compiled tcc is [[https://lists.gnu.org/archive/html/tinycc-devel/2017-05/msg00103.html][known]] to compile GCC.

Mes is inspired by The Maxwell Equations of Software: [[http://www.softwarepreservation.org/projects/LISP/book/LISP%2525201.5%252520Programmers%252520Manual.pdf][LISP-1.5]] -- John
McCarthy page 13, GNU Guix's source/binary packaging transparency and
Jeremiah Orians's stage0 ~300 byte self-hosting hex assembler.
