1.: 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 bison version needs the m4 program as
back end to generate the parser file (y.tab.c etc.) from the skeleton
files. This implies that m4 must always be installed to get bison
/dev/env/DJDIR/share/bison and shall not be removed.
It should also be noticed that the skeleton files bison.simple and
bison.hairy are no longer supported. This applies also to the environ-
- ment variables BISON_HAIRY and BISON_SIMPLE. Those variables are *no*
+ ment variables BISON_HAIRY and BISON_SIMPLE. Those variables are *no*
longer honored at all.
The kind of skeleton file bison.hairy is no longer supported at all.
The skeleton file bison.simple is now called yacc.c and is an m4 script.
This is done by forking and using pipes for the IPC. MSDOS does not
support this functionality so this has been reproduced in the usual
way by redirecting stdin and stdout of bison and m4 to temporary files
- and processing these files in sequence. All the changes to the sources
- are documented in the djgpp/diffs file.

with the necessary mappings. So you need first to retrieve that batch
file, and then invoke it to unpack the distribution. Here's how:
- djtar -x -p -o bison-2.1/djgpp/djunpack.bat bison-2.1.tar.gz > djunpack.bat
- djunpack bison-2.1.tar.gz
+ djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar.gz > djunpack.bat
+ djunpack bison-@VERSION@.tar.gz
(The name of the distribution archive and the leading directory of the
path to `djunpack.bat' in the distribution will be different for
- versions of Bison other than 2.1.)
+ versions of Bison other than @VERSION@.)
If the argument to `djunpack.bat' include leading directories, it MUST
be given with the DOS-style backslashes; Unix-style forward slashes
`djtar' doesn't support bzip2 decompression, you need to unpack it as
follows:
- bnzip2 bison-2.1.tar.bz2
- djtar -x -p -o bison-2.1/djgpp/djunpack.bat bison-2.1.tar > djunpack.bat
- djunpack bison-2.1.tar
+ bnzip2 bison-@VERSION@.tar.bz2
+ djtar -x -p -o bison-@VERSION@/djgpp/djunpack.bat bison-@VERSION@.tar > djunpack.bat
+ djunpack bison-@VERSION@.tar
3.3.: To build the binaries you will need the following binary packages:
djdev203.zip (or a later but NOT a prior version)
bsh204b.zip (or a later but NOT a prior version)
- gcc400b.zip, gpp400b.zip, bnu215b.zip, mak3791b.zip,
- fil40b.zip, shl20jb.zip, txt20b.zip,
- txi48b.zip, grep24b.zip, sed414b.zip,
- m4-144b.zip.
+ gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip,
+ perlNNNb.zip, shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip,
+ sedNNNb.zip and m4NNN.zip
If you want to run the check you will need also:
- dif281b.zip
+ difNNNb.zip

3.4.: If for some reason you want to reconfigure the package cd into the top
srcdir (bison-@TREE_VERSION@) and run the following commands:
command:
make check

- Please note that the testsuite only works with LFN available. On plain
- DOS, most of the tests will fail due to invalid DOS names.

3.7.: To install the binaries, header, library, catalogs, and info docs
run the following command from the top srcdir:
