interfaces. * data/bison.m4 (b4_percent_define_get_loc): New. (b4_percent_define_get_syncline): New. (b4_percent_define_flag_if): Use b4_percent_define_get_loc.

(muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and remove some unused variables.

(Complaining during macro argument expansion): Extend to test b4_percent_define_get_loc and b4_percent_define_get_syncline errors.
-*- outline -*- 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. ----- Copyright (C) 2002 Free Software Foundation, Inc. This file is part of GNU Bison.
