+Building older GNU coreutils versions on newer systems
+======================================================
+
+Overview
+--------
+
+Some older GNU coreutils fail to build on newer GNU/Linux systems.
+
+This happens with Coreutils version 8.29 and earlier, on systems
+using GlibC version 2.28 or newer, Such as Debian 10, CentOS 8, Fedora 29.
+
+A typical error is:
+
+ $ wget https://ftp.gnu.org/gnu/coreutils/coreutils-7.6.tar.xz
+ $ tar -xf coreutils-7.6.tar.xz
+ $ cd coreutils-7.6
+ $ ./configure
+ $ make
+ [...]
+ freadahead.c: In function 'freadahead':
+ freadahead.c:83:3: error: #error "Please port gnulib freadahead.c to
+ your platform! Look at the definition of fflush,
+ fread, ungetc on your system, then report this
+ to bug-gnulib."
+ [...]
+ make[4]: *** [Makefile:1700: freadahead.o] Error 1
+
+Other similar errors mention 'freadptr', 'freadseek','fseterr'.
+Older version (pre 7.2) mention 'tee','eaccess','futimens'.
+
+
+Details
+-------
+
+GLibC version 2.28 removed non-standed headre file (libio.h) and some
+internal symbols which were used by gnulib (a core component of GNU coreutils).
+
+These were announced as 'deprecated' in vesion 2.27 [1], and removed in
+version 2.28. Gnulib code was adjusted shortly after [2],
+but the code changes obviously can't be retroactively made to
+previously-released coreutils versions.
+
+[1] https://sourceware.org/ml/libc-announce/2018/msg00000.html
+[2] https://lists.gnu.org/r/bug-gnulib/2018-03/msg00000.html
+
+Older coreutils versions defined functions that were later picked-up
+by glibc ('tee','eaccess','futimens') resulting in conflicts.
+
+See the patches for the exact code changes.
+
+
+Supplied patches
+----------------
+
+The patch files in this directory change the source code of older
+coreutils versions, enabling successful build on newer systems.
+
+Some versions require different patches.
+
+Coreutils Versions Patch file
+5.0 coreutils-5.0-on-glibc-2.28.diff
+5.97 to 6.9 coreutils-5.97-on-glibc-2.28.diff
+6.10 coreutils-6.10-on-glibc-2.28.diff
+6.11 coreutils-6.11-on-glibc-2.28.diff
+6.12 coreutils-6.12-on-glibc-2.28.diff
+7.2 to 8.3 coreutils-7.2-on-glibc-2.28.diff
+8.4 to 8.12 coreutils-8.4-on-glibc-2.28.diff
+8.13 to 8.16 coreutils-8.13-on-glibc-2.28.diff
+8.17 coreutils-8.17-on-glibc-2.28.diff
+8.18 to 8.23 coreutils-8.18-on-glibc-2.28.diff
+8.24 to 8.29 coreutils-8.24-on-glibc-2.28.diff
+8.30 and newer [builds without patching]
+
+
+Manual build
+------------
+
+1. Download the desired version from https://ftp.gnu.org/gnu/coreutils .
+2. Patch using the corresponding patch file (see table above).
+3. Configure the build, optionally adding the version number
+ to the executables, to ensure they will not conflict with existing
+ (newer) executables
+4. Build with 'make'
+5. Optionally install with 'sudo make install'
+
+Example:
+
+ wget https://ftp.gnu.org/gnu/coreutils/coreutils-5.97.tar.gz
+ tar -xf coreutils-5.97.tar.gz
+ cd coreutils-5.97
+ patch -p1 < ../coreutils-5.97-on-glibc-2.28.diff
+ ./configure --program-suffix=-5.97
+ make
+ sudo make install
+
+This will install the programs (e.g. 'sort', 'head) in
+/usr/local/bin, with "-5.97" added to each program name (e.g. 'sort-5.97',
+'head-5.97').
+
+NOTE:
+With very old versions (5.X and 6.X), running "./configure" will
+hang for a long time at the following step:
+ "checking for mktime..."
+But will eventually continue successfully.
+
+
+Automated build
+---------------
+
+The script 'build-older-versions.sh' automatically performs the manual steps
+listed above. The script installs each package in a separate directory:
+Programs in `$HOME/old-coreutils/coreutils-{VERSION}/bin`,
+manual pages in `$HOME/old-coreutils/coreutils-{VERSION}/share/man`,
+PDF manual in `$HOME/old-coreutils/coreutils-{VERSION}/share/doc`,
+INFO pages in `$HOME/old-coreutils/coreutils-{VERSION}/share/info`.
+It will also create symlinks to all version in a common directory
+`$HOME/old-coreutils/bin`.
+
+Example, running the following commands:
+
+ ./build-older-versions.sh 5.0
+ ./build-older-versions.sh 5.97
+ ./build-older-versions.sh 6.12
+ ./build-older-versions.sh 7.6
+
+Will download, patch, build and install the programs for GNU coreutils
+versions 5.0,5.97,6.12,7.6 in `$HOME/old-coreutils/bin` :
+
+ $ ls $HOME/old-coreutils/bin
+ [-5.97 id-5.0 sha224sum-7.6
+ [-6.12 id-5.97 sha256sum-6.12
+ [-7.6 id-6.12 sha256sum-7.6
+ base64-6.12 id-7.6 sha384sum-6.12
+ base64-7.6 install-5.0 sha384sum-7.6
+ basename-5.0 install-5.97 sha512sum-6.12
+ basename-5.97 install-6.12 sha512sum-7.6
+ basename-6.12 install-7.6 shred-5.0
+ basename-7.6 join-5.0 shred-5.97
+ cat-5.0 join-5.97 shred-6.12
+ cat-5.97 join-6.12 shred-7.6
+ cat-6.12 join-7.6 shuf-6.12
+ cat-7.6 kill-5.0 shuf-7.6
+ chcon-6.12 kill-5.97 sleep-5.0
+ chcon-7.6 kill-6.12 sleep-5.97
+ chgrp-5.0 kill-7.6 sleep-6.12
+ chgrp-5.97 link-5.0 sleep-7.6
+ chgrp-6.12 link-5.97 sort-5.0
+ chgrp-7.6 link-6.12 sort-5.97
+ chmod-5.0 link-7.6 sort-6.12
+ chmod-5.97 ln-5.0 sort-7.6
+ chmod-6.12 ln-5.97 split-5.0
+ chmod-7.6 ln-6.12 split-5.97
+ chown-5.0 ln-7.6 split-6.12
+ [... many more files ...]
+
+By adding the directory to your $PATH, older versions can be easily used:
+
+ export PATH=$PATH:$HOME/old-coreutils/bin
+ export MANPATH=$MANPATH:$HOME/old-coreutils/man
