never deeper than 1; instead, use the new auto var c_context to record the stacked value. Remove nounput option. At an unexpected end of file, we now unput the minimal input necessary to end cleanly; this simplifies the code. Avoid unbounded token sizes where this is easy. (unexpected_end_of_file): New function. Use it to systematize the error message on unexpected EOF. (last-string): Now auto, not static. (YY_OBS_FREE): Remove unnecessary do while (0) wrapper. (scanner_last_string_free): Remove; not used. (percent_percent_count): Move decl to just before use. (SC_ESCAPED_CHARACTER): Return ID at unexpected end of file, not the (never otherwised-used) CHARACTER.
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.
