* doc/bison.1 (mandoc): Update.
* src/system.h (EXT_GUARD_C, EXT_STYPE_H): Remove .c and .h.
* src/files.c: Support output files extensions computing.
(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'.
* src/lex.c (parse_percent_token): Die on `%raw'.
* src/reader.c (output_token_defines): Suppress call to `raw_flag'.
* tests/calc.at: Suppress test with option `--raw'.
New, from fileutils 4.0.37.
* configure.in: Require Autoconf 2.49c. I took some time before
making this decision. This is the only way out for portability
issues in Bison, it would mean way too much duplicate effort to
import in Bison features implemented in 2.49c since 2.13.
AC_REPLACE_FUNCS and AC_CHECK_DECLS the functions above.
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.
