This is a port of GNU make 4.1  to MSDOS/DJGPP.

  Make is a program for building other programs, given a description of
  the dependencies between the files.



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

        The most important DJGPP specific change is that I have removed the
        dependence of guile.  AFAIK there is no DJGPP port of guile and I
        assume that there will never be.  This means that all make extensions
        that require the use of guile will never be available for DJGPP.

        The test suite requires perl and fails completely.  This is because it
        checks for the perl fork() functionality that is not supported by the
        current DJGPP port of perl.

        The port now uses the same configuration files than most of all the
        other DJGPP ports.  These files are stored together with the diffs
        file in the /djgpp directory.  This has the benefity that it becomes
        easier to support NLS and other features that may require to adjust
        the configure script and the Makefile.ins.  The original build system
        is fully functional and supported by this port.

        The source package is configured to be build in the "_build.204" directory.

        The port has been configured and compiled with NLS support enabled using
        the latest ports of libiconv and gettext.

          ftp://ftp.delorie.com/pub/djgpp/beta/v2gnu/gtxt192b.zip
        If you prefer to compile a version without NLS support use the original
        build system.
        Please note that because the port has been compiled with NLS support
        using the DXE3 module versions of the gettext and iconv libraries it
        is MANDATORY to install both gtxt192b and licv114br2 ports or the make
        program will not work at all.

        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 2.04 version of the port has been compiled using gcc490 and
        bnu224br2.  But instead of using the libc.a provided djdev204, a libc
        version compiled from the repository code has been used. The repository
        code has been patched with the memory patch as provided by Andris
        Pavenis in:
          http://ap1.pp.fi/djgpp/djdev/djgpp/20140421/use_nmalloc.diff
        The goal is to test how well the new memory system and the current libc
        code works.  The repository code can be downloaded from Martin Stromberg's
        site as:
          http://www.ludd.luth.se/~ams/djgpp/cvs/djgpp.cvs.tar.gz 

        As usual, all djgpp specific files (config.bat, diffs, README files,
        etc.) are located in the /djgpp directory.

        For further information about GNU make 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,
        just unzip it preserving the directory structure running *ONE* of the
        following commands:
          unzip32 mak41b.zip      or
          djtarx mak41b.zip       or
          pkunzip -d mak41b.zip


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 mak41s.zip      or
          djtarx mak41s.zip       or
          pkunzip -d mak41s.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 configure and compile this packages with NLS support
        enabled you must install licvNNNb.zip, lunsNNNb.zip and gtxNNNNb.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 make-4.1).  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 nls.  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\make-4.1\djgpp\config x:/src/gnu/make-4.1

        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\make-4.1\djgpp\config x:/src/gnu/make-4.1

        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.

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

3.5.:   The test suite does not work at all due to limitations inherent to the
        DJGPP port of perl  (fork not supported).

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
