Joel E. Denny 7ecec4ddf9 Simplify union and prologue handling, and escape union and lex/parse
params with digraphs.
* data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default
values to the empty string since these are no longer guaranteed
initialized by the front-end.
* data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add
braces around b4_user_stype since this is no longer done by the
front-end.
* src/files.c, src/files.h (pre_prologue_obstack,
post_prologue_obstack): Remove.
* src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header
comments here.  Use MUSCLE_OBSTACK_SGROW so that values are escaped
with digraphs.  This fixes lex params and parse params.
* src/muscle_tab.h (muscle_pair_list_grow): Update comments.
* src/output.c (prepare): Remove muscle insertion of the prologues.
(output): Remove freeing of pre_prologue_obstack and
post_prologue_obstack.
* src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather
than prologue_augment for prologue parsing so you don't need prologue
obstacks.
(grammar_declaration): Use `braceless' instead of "{...}" so that
braces are already stripped and code is escaped with digraphs.
* src/reader.c (prologue_augment): Remove.
(reader): Remove initialization of pre_prologue_obstack and
post_prologue_obstack.
* src/reader.h (prologue_augment): Remove.

* data/c.m4: Remove stray parenthesis.

This directory contains Bison skeletons: the general shapes of the
different parser kinds, that are specialized for specific grammars by
the bison program.

Currently, there are only three supported skeletons:

- yacc.c
  It used to be named bison.simple: it corresponds to C Yacc
  compatible LALR(1) parsers.

- lalr1.cc
  Produces a C++ parser class.  It is still very experimental, and not
  yet supported.  Please, subscribe to bison-patches@gnu.org.

- glr.c
  A Generalized LR C parser based on Bison's LALR(1) tables.

These skeletons are the only ones supported by the Bison team.
Because the interface between skeletons and the bison program is not
finished, *we are not bound to it*.  In particular, Bison is not
mature enough for us to consider that ``foreign skeletons'' are
supported.
