Jan Nieuwenhuizen ddd880bdc8 mescc: Remove last hardcodings for identifiers. 
* module/language/c99/compiler.mes (ident->accu, ident->base):
  Use local:ptr, type->size to remove hard coding of functionx, c1.
  (expr->accu): Use type->size to remove hard coding of size byte.
  (decl->type): Also handle typename, bail out if type not found.
  (type->size): Print identifier and and bail out if type not found.
  (formal:ptr): New function.
  (formals->locals): Use it to set pointer value of parameter.  WAS: 0.
  (ast->info): Remove functionx hardcoding.
  (getchar): Rename c1 to c.
* doc/examples/t.c: Test it.

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.

It currently has an interpreter written in C (mes) with Garbage
Collector (Jam Scraper), a library of loadable Scheme modules--
notably [[https://github.com/schemeway/lalr-scm][Dominique Boucher's LALR]], [[https://www.cs.indiana.edu/chezscheme/syntax-case/old-psyntax.html][Pre-R6RS portable syntax-case]] with
R7RS ellipsis, [[http://www.nongnu.org/nyacc/][Nyacc]] and [[https://www.gnu.org/software/guile/docs/master/guile.html/PEG-Parsing.html][Guile's PEG]] --and test suite just barely
enough to support a simple REPL (repl.mes) and a proof-of-concept
C-compiler (mescc.mes) that produces an elf from the simplest of C
files.

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.

General Public Licence version 3 or later.  See the file COPYING.
