This is a port of GNU patch 2.7.1 to MSDOS/DJGPP.

  This is GNU patch, which applies diff files to original files.



1.:     DJGPP specific changes.
        =======================

        - support for numbered backups even on 8+3 file systems.

        - Patch can now ignore the CR characters at the end of each line
          of the patch script, so patching Unix-style text files does not
          convert them to DOS-style files anymore (if you use the --binary
          switch).

        - This port no longer supports neither DJGPP 2.03 nor DJGPP 2.04.  This
          port has been configured using DJGPP 2.05.  It has been configured to
          be build in the "_build.205" directory.

        - The port has been configured and compiled on WinXP SP3.  There is no
          guarantee that this may be possible with any other DOS-like OS.  Due
          to the use of long file names it will not be possible to configure
          and compile without LFN support.

        - The DJGPP 2.05 version of the port has been compiled using gcc510 and
          bnu225br2.

        As usual, all djgpp specific files (config.bat, diffs, readme files,
        etc.) are located in the /djgpp directory. The directory /pc/djgpp
        contains djgpp specific files shipped with the original FSF distribution
        and these are not used by this port.  Most of them probably do not work
        any longer.

        For further information about GNU patch please read the info docs
        and NEWS file.


2.:     Installing the binary package.
        ==============================

2.1.:   Copy the binary distribution into the top DJGPP installation directory
        and unzip it running one of the following commands:
          unzip32 pat275br2.zip      or
          djtarx pat275br2.zip       or
          pkunzip -d pat275br2.zip

        For further information about GNU patch please read the man page
        and the NEWS file.


3.:     Building the binaries from sources.
        ===================================

3.1.:   Create a temporary directory and copy the source package into the
        directory.  If you download the source distribution from one of the
        DJGPP sites, just unzip it preserving the directory structure
        running *ONE* of the following commands:
          unzip32 pat275sr2.zip      or
          djtarx pat275sr2.zip       or
          pkunzip -d pat275sr2.zip

3.2.:   To build the binaries you will need the following binary packages:
          djdev203.zip (or a later but NOT a prior version)
          bsh205bbr3.zip (or a later but NOT a prior version)
          gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip,
          shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip, sedNNNb.zip,
          pcreNNNb.zip, mktmpNNb.zip and gwkNNNb.zip.

        If you want to run the check you will need also:
          difNNNb.zip and mktmpNNNb.zip

        NNN represents the latest version number of the binary packages.  All
        this packages can be found in the /v2gnu directory of any
        ftp.delorie.com mirror.
        You will need bsh205bbr3.zip or later and *NOT* a prior version or
        the build will fail.  The same applies to djdev203.zip.

3.3.:   The package has been configured for both DJGPP 2.03 and DJGPP 2.04.
        There is a separate build directory for DJGPP 2.03 and for DJGPP 2.04
        under the top srcdir (aka patch-2.7.1).  To build the binaries
        using the 2.03 version of DJGPP cd into _build.203; if you prefer to
        build the binaries using DJGPP 2.04 cd into _build.204.  If for some
        reason you want to reconfigure the package cd into the corresponding
        build directory and run the following commands:
          del config.cache
          make clean
          ..\djgpp\config ./..

        Please note that you *MUST* delete the config.cache file in the djgpp
        subdir or you will not really reconfigure the sources because the
        configuration informations will be read from the cache file instead
        of being newly computed.

        config.bat, among other things, will start the configure script passing
        to it a couple of arguments.  You can control these argument passing the
        following command line arguments to config.bat:
          nls or no-nls, default no-nls.  No NLS support.
          cache or no-cache, default cache.
          dep or no-dep, default no-dep.  No dependency tracking.
        All other configure specific options are not set by config.bat so their
        values are left as they are.  If no arguments are passed to config.bat
        then the default values are used.


        To build the programs in a directory other than where the sources are,
        you must add the parameter that specifies the source directory,
        e.g:
          x:\src\gnu\patch-2.7.1\djgpp\config x:/src/gnu/patch-2.7.1

        Lets assume you want to build the binaries in a directory placed on a
        different drive (z:\build in this case) from where the sources are,
        then you will run the following commands:
          z:
          md \build
          cd \build
          x:\src\gnu\patch-2.7.1\djgpp\config x:/src/gnu/patch-2.7.1

        The order of the options and the srcdir option does not matter.  You
        *MUST* use forward slashes to specify the source directory.

        The batch file will set same environment variables, make MSDOS specific
        modifications to the Makefile.in's and supply all other needed options
        to the configure script.


3.3.:   This package does not have NLS support.
        If for some reason you want to reconfigure the package cd into the top
        srcdir (patch-2.7.1) and run the following commands:
          del djgpp\config.cache
          make distclean
          djgpp\config

        Please note that you *MUST* delete the config.cache file in the djgpp
        subdir or you will not really reconfigure the sources because the
        configuration informations will be read from the cache file instead
        of being newly computed.
        To build the programs in a directory other than where the sources are,
        you must add the parameter that specifies the source directory,
        e.g:
          x:\src\gnu\patch-2.7.1\djgpp\config x:/src/gnu/patch-2.7.1

        Lets assume you want to build the binaries in a directory placed on a
        different drive (z:\build in this case) from where the sources are,
        then you will run the following commands:
          z:
          md \build
          cd \build
          x:\src\gnu\patch-2.7.1\djgpp\config x:/src/gnu/patch-2.7.1

        The order of the options and the srcdir option does not matter. You
        must use forward slashes to specify the source directory.

        The batch file will set same environment variables, make MSDOS specific
        modifications to the Makefile.ins and supply all other needed options
        to the configure script.

3.4.:   To compile the package run from the directory where you have configured
        the sources the command:
          make

3.5.:   Now you can run the tests if you like.  Start the command:
          make check

        The following tests will fully or partially fail:
          crlf-handling, preserve-mode-and-timestamp, file-modes and fifo.
        For the 2.03 port also the symlink test will fail.
        This is not a port issue.

3.6.:   To install the binaries and info docs run the following command from
        the directory where you have configured the sources:
          make install

        This will install the products into your DJGPP installation tree given
        by the default prefix "/dev/env/DJDIR".  If you prefer to install them
        into some other directory you will have to set prefix to the appropriate
        value:
          make install prefix=z:/some/other/place
