errtoken->number. * src/reader.c (reader): Don't specify the user token number (2) for $undefined, as it uselessly prevents using it. * src/gram.h (token_number_t): Move to... * src/symtab.h: here. (state_t.number): Is a token_number_t. * src/print.c, src/reader.c: Use undeftoken->number instead of hard coded 2. (Even though this 2 is not the same as above: the number of the undeftoken remains being 2, it is its user token number which might not be 2). * src/output.c (prepare_tokens): Rename the `maxtok' muscle with `user_token_number_max'. Output `undef_token_number'. * data/bison.simple, data/bison.c++: Use them. Be sure to map invalid yylex return values to `undef_token_number'. This saves us from gratuitous SEGV. * tests/conflicts.at (Solved SR Conflicts) (Unresolved SR Conflicts): Adjust. * tests/regression.at (Web2c Actions): Adjust.
This directory contains the Bison parser generator. See the file INSTALL for compilation and installation instructions. See the file doc/FAQ for frequently asked questions. It was once true that, when installing Bison on Sequent (or Pyramid?) systems, you had to be in the Berkeley universe. This may no longer be true; we have no way to tell. On VMS, you will probably have to create Makefile from Makefile.in by hand. Remember to do `SET COMMAND BISON' to install the data in `BISON.CLD'. VMS and MS-DOS builds are probably broken right now. If you are able to build Bison on either platform and you need to make changes to do so, please submit those changes as a bug report. Send bug reports to bug-bison@gnu.org. Please include the version number from `bison --version', and a complete, self-contained test case in each bug report. If you have questions about using Bison which the documentation does not answer, send mail to help-bison@gnu.org.
