Akim Demaille 8f7e3cf9d0 Have glr.cc pass (some of) the calc.at tests.
* data/glr.cc (b4_parse_param_orig): New.
(b4_parse_param): Improve its definition, and bound it more
clearly in the skeleton.
(b4_epilogue): Append, instead of prepending, in order to keep
#line consistency.
Simplify the generation of auxiliary functions: locations and
purity are mandated.
(b4_global_tokens_and_yystype): Honor it.
* data/location.cc (c++.m4): Don't include it.
* tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Define AT_GLR_CC_IF
and AT_SKEL_CC_IF.
* tests/calc.at (AT_CHECK_CALC): Rely on AT_SKEL_CC_IF instead of
AT_LALR1_CC_IF.
Be sure to initialize the first position's filename.
(AT_CHECK_CALC_LALR1_CC): Add %location and %defines, they are
mandated anyway.
(AT_CHECK_CALC_GLR_CC): New.
Use it to exercise glr.cc as a lalr1.cc drop-in replacement.

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.
