Jan Nieuwenhuizen 38dc229a01 mescc: Have micro-mes use if not to segfault.
* module/language/c99/compiler.mes (write-any): Check explicitly on
  number?, report error otherwise.
  (statement->text+symbols+locals): Remove statement-offset.
  Handle compounds.  Handle very specific if.
  (function->symbols): Remove unused text-offset.
* doc/examples/micro-mes.c (main): If argc > 1 print argv1.  Fixes
  segfault :-)
* module/mes/elf-util.mes (symbols->text): Loop rather than map,
  feed text-offset.

  immediate, initialize with local.
  (formals->locals): Bugfix: formals counted down from -1 [WAS: down to
