This is a port of GNU Bison 1.875 to MSDOS/DJGPP.


  DJGPP specific changes.
  =======================

  - The DJGPP port of Bison offers LFN and SFN support depending on which OS it
    is running.  If LFN support is available or not is determinated at run time.
    If LFN support is available (DOS session under Win9X), the standard posix
    file name extensions will be used. These are: y.tab.c, y.tab.c++, y.tab.h,
    y.output, etc. If only SFN support is available (plain DOS), then the
    standard MSDOS short file names will be used. These are: y_tab.c, y_tab.h,
    y.out, etc.
  - It should be noticed that this version of Bison uses the m4 program as a
    backend to generate the parser file (e.g. y_tab.c, etc.) from the skeleton
    files. This means that m4 *must* be installed and available when bison's is
    invoked or bison will not be able to generate the parser file. m4 will use
    a couple m4 scripts that will be installed in /dev/env/DJDIR/share/bison.
  - It should also be noticed that the two skeleton files bison.simple and
    bison.hairy are no longer used nor supported anymore. This applies also to
    the two environment variables BISON_HAIRY and BISON_SIMPLE. Those variables
    are *no* longer honored at all. This implies that you can no longer use
    these variables to point bison to an alternative skeleton file. Use the
    command line option `-S' instead.
  - The skeleton file bison.simple is now called yacc.c and is an m4 script.
    Please notice that the grammar type coded in the skeleton file bison.hairy
    is no longer supported by the bison maintainer. The other two skeleton
    files supported by this bison version are glr.c and lalr1.cc. The first one
    is a generalized LR C parser based on Bison's LALR(1) tables and the second
    one is a experimental C++ parser class.


  For futher information about GNU bison please read the info docs and NEWS file.


  Please also note that the testsuite will only work if LFN are available.
