the source or/and the header output file extension.
* src/files.c (compute_base_names): Remove initialisation of
src_extension and header_extension.
(compute_exts_from_gf): Update.
(compute_exts_from_src): Update.
(output_files): Update.
* src/reader.c (parse_header_extension_decl): New.
(parse_source_extension_decl): New.
(read_declarations): New case statements for the new tokens.
* src/lex.c (percent_table): Add entries for %source_extension
and %header_extension.
* src/lex.h (token_e): New tokens tok_hdrext and tok_srcext.
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.
(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.
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.
* src/files.c (obstack_save): New function.
(done): Rename as...
(output_files): this.
Use `obstack_save'.
* src/main.c (main): Don't use `atexit' to register `done', since
it no longer has to remove tmp files, just call `output_files'
when there are no errors.
* src/files.c (fdefines, ftable): Removed.
(defines_ostack, table_obstack): New.
Adjust dependencies of the former into uses of the latter.
* src/output.c (output_short_or_char_table, output_short_table):
Convert to using obstacks.
* src/reader.c (copy_comment2): Accept one FILE * and two
obstacks.
(output_token_defines, reader_output_yylsp): Use obstacks.
* src/system.h (obstack_fgrow3): New.
