Using option ``-g'' or long option ``--graph'', you can generate
a gram_filename.vcg file containing a VCG description of the LALR (1)
automaton of your grammar.

(src_extension): New static variable.
(header_extension): New static variable.
(tr): New function.
(get_extension_index): New function, gets the index of an extension
filename in a string.
(compute_exts_from_gf): New function, computes extensions from the
grammar file extension.
(compute_exts_from_src): New functions, computes extensions from the
C source file extension, file given by ``-o'' option.
(compute_base_names): Update.
(output_files): Update.
* src/getargs.c: Die on `-r'/`--raw'.

the obstacks.
* src/lex.c (token_obstack): New.
(init_lex): Initialize it. No longer call...
(grow_token_buffer): this. Remove it.
Adjust all the places which used it to use the obstack.
* src/lex.c (percent_table): Also accept `%yacc',
`%fixed_output_files', `%defines', `%no_parser', `%verbose', and
`%debug'.
Handle the actions for `%semantic_parser' and `%pure_parser' here,
instead of returning a token.
* src/lex.h (SEMANTIC_PARSER, PURE_PARSER): Remove, unused.
* src/reader.c (read_declarations): Adjust.
* src/files.c (open_files): Don't call `compute_base_names', don't
compute `attrsfile' since they depend upon data which might be
*in* the input file now.
(output_files): Do it here.
* src/output.c (output_headers): Document the fact that this patch
introduces a guaranteed SEGV for semantic parsers.
* doc/bison.texinfo: Document them.
* tests/suite.at: Exercise these %options.
* files.c (foutput): Remove.
(output_obstack): New.
Adjust all dependencies.
* src/conflicts.c: Return a string.
* src/system.h (obstack_grow_string): Rename as...
(obstack_sgrow): this. Be ready to work with non literals.
(obstack_fgrow4): New.
(stringappend): Be just like strcat but allocate.
(base_names): Eve out from open_files.
Try to simplify the rather hairy computation of base_name and
short_base_name.
(open_files): Use it.
* tests/suite.at (Checking output file names): New test.
that use it.
* src/files.c (xfopen, xfclose, skeleton_find, guardfile): No
longer static.
(fparser, open_extra_files): Remove.
(open_files, output_files): Don't take care of fparser.
* src/files.h: Adjust.
* src/output.c (output_parser): Open and close the file to the
skeleton.
* src/reader.c (read_declarations): When %semantic_parser, open
fguard.
Provide a default definition.
Use it when executing the default @ action.
* src/reader.c (reader_output_yylsp): No longer include
`timestamp' and `text' in the default YYLTYPE.
to escape special characters when outputting filenames.
(ACTSTR_PROLOGUE, ACTSTR_EPILOGUE): Remove.
(output_headers): Don't depend on them, Use ACTSTR.
(obstack_grow, obstack_grow0): Don't cast WHERE at all: it
prevents type checking.
(obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
cast the value to (void *): assigning a `foo *' to a `void *'
variable is valid.
(obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.
* src/reader.c (parse_union_decl): Typo: use obstack_1grow to
append characters.
