* data/bison.simple, data/bison.c++: Use `b4_pre_prologue' and
`b4_post_prologue' instead of `b4_prologue'.
* src/output.c (prepare): Add the `pre_prologue' and `post_prologue'
muscles.
(output): Free pre_prologue_obstack and post_prologue_obstack.

obstack to fill, instead of using attrs_obstack unconditionally.

`%union' has not yet been seen, pass post_prologue_obstack otherwise.
(MUSCLE_INSERT_PREFIX): ...to there.
* src/output.c (MUSCLE_INSERT_INT, MUSCLE_INSERT_STRING)
(MUSCLE_INSERT_PREFIX): Move from here...
* src/bison.hairy: Add a section directive. Put braces around muscle
names. This parser skeleton is still broken, but Bison should not
choke on a bad muscle 'syntax'.
* src/bison.simple: Add a section directive. Put braces around muscle
names.
* src/files.h (strsuffix, stringappend): Add declarations.
(tab_extension): Add declaration.
(short_base_name): Add declaration.
* src/files.c (strsuffix, stringappend): No longer static. These
functions are used in the skeleton parser.
(tab_extension): New.
(compute_base_names): Use the computations done in this function
to guess if the generated parsers should have '.tab' in their
names.
(short_base_name): No longer static.
* src/output.c (output_skeleton): New.
(output): Disable call to output_master_parser, and give a try to
a new skeleton handling system.
(guards_output, actions_output): No longer static.
(token_definitions_output, get_lines_number): No longer static.
* configure.in: Use AM_PROG_LEX and AC_PROG_YACC.
* src/Makefile.am (bison_SOURCES): Add scan-skel.l and
parse-skel.y.
* src/parse-skel.y: New file.
* src/scan-skel.l: New file.
obstack. It was done too late here.
* src/reader.c (parse_macro_decl): Fix. Use of the macro obstack was
completely wrong.
(reader): Initialize the macro obstack here, since we need it to grow
'%define' directives.
* src/reader.h: Declare the macro obstack as extern.
'output_trailers'. Remove some C output.
(readgram): Disable a piece of code that was writing a default
definition for 'YYSTYPE'.
(reader_output_yylsp): Remove.
(packsymbols): Output token defintions to a macro.
(copy_definition): Disable C output.
* src/reader.c (parse_macro_decl): New function used to parse macro
declarations.
(copy_string2): Put the body of copy_string into this new function.
Add a parameter to let the caller choose whether he wants to copy the
string delimiters or not.
(copy_string): Be a simple call to copy_string2 with the last argument
bound to true.
(read_declarations): Add case for macro definition.
(copy_identifier): New.
(parse_macro_decl): Read macro identifiers using copy_identifier
rather than lex.
(output_parser): Output semantic actions.
(output_parser): Fix bug on '%%line' directives.
* src/output.c (output_headers): Remove. The C code printed by this
function should now be in the skeletons.
(output_trailers): Remove.
(output): Disable call to 'reader_output_yylsp'.
(output_rule_data): Do not output tables to the table obstack.
* src/output.c: Remove some C dedicated output.
Improve the use of macro and output obstacks.
(output_defines): Remove.
* src/output.c (output_token_translations): Associate 'translate'
table with a macro. No output to the table obstack.
(output_gram): Same for 'rhs' and 'prhs'.
(output_stos): Same for 'stos'.
(output_rule_data): Same for 'r1' and 'r2'.
(token_actions): Same for 'defact'.
(goto_actions): Same for 'defgoto'.
(output_base): Same for 'pact' and 'pgoto'.
(output_table): Same for 'table'.
(output_check): Same for 'check'.
* src/output.c (output_table_data): New function.
(output_short_table): Remove.
(output_short_or_char_table): Remove.
* src/output.c (output_parser): Replace most of the skeleton copy code
with something new. Skeletons are now processed character by character
rather than line by line, and Bison looks for '%%' macros. This is the
first step in making Bison's output process (a lot) more flexible.
(output_parser): Use the macro table.
* src/output.c (prepare): Add prefixed names.
(output_parser): Output semantic actions.
(output_parser): Fix bug on '%%line' directives.
