commit 11444fb001cf57f32fb5022cd934c3cf489e66b2
Author: Paul Smith <psmith@gnu.org>

    [SV 62654] Support GNU Make on z/OS
    
    Original patches provided by Igor Todorovski <itodorov@ca.ibm.com>
    Reworked by Paul Smith <psmith@gnu.org>.
    Thanks to IBM for providing a test system.
    
    * NEWS: Announce support.
    * AUTHORS: Ditto.
    * README.zOS: Provide details on building GNU Make on z/OS.
    * build.sh (get_mk_var): z/OS sh has a strange bug which causes it to
    generate extra lines of output: rework the function to print output
    as we compute it instead of collecting it into a variable, which
    works around this bug.
    * src/makeint.h: Declare MK_OS_ZOS if we're building for z/OS.
    * src/arscan.c: Don't include <ar.h> on z/OS.
    * src/job.c: We can't change environ in ASCII mode on z/OS.
    * src/main.c: Ditto.  Also we can't use pselect() on z/OS.
    * src/posixos.c: pselect() seems to hang on z/OS: don't use it.
    * tests/run_make_tests.pl: Handle different exit codes on z/OS.
    * tests/test_driver.pl: Preserve some special z/OS env.vars.
    Add special checks to output comparisons when on z/OS.
    * tests/scripts/features/archives: Don't validate names.  Don't
    try to compile empty files as IBM compilers complain.
    * tests/scripts/features/shell_assignment: Fix octal value of #.
    * tests/scripts/features/temp_stdin: Don't print "term".
    * tests/scripts/functions/shell: Handle shell exit codes.
    * tests/scripts/targets/ONESHELL: Ditto.
    * tests/scripts/targets/POSIX: sh -x prints differently.
    * tests/scripts/variables/SHELL: Ditto.

commit 0de7a0d3bf29a240c5e0fef79b5b3eae8a6a01f5
Author: Paul Smith <psmith@gnu.org>
Date:   Sun Jan 8 09:38:59 2023 -0500

    Create src/mkcustom.h which is included by config.h
    
    Put declarations for missing functions which we create in src/misc.c
    into a file which is included by config.h via AH_BOTTOM().  This
    ensures those prototypes are available, even in files added to
    lib/... from gnulib.
    
    * src/mkcustom.h: Add a new file with function declarations.
    * configure.ac: Include src/mkcustom.h in config.h with AH_BOTTOM()
    * Makefile.am: Add the header to the SRCS list.
    * src/makeint.h: Remove content that we added to src/mkcustom.h.
    * src/config.ami: Add #include "mkcustom.h" to specialized config.h.
    * src/config.h-vms: Ditto.
    * src/config.h.W32: Ditto.
    * src/configh.dos: Ditto.

commit 1656cd051c7f28de359b1f188b20a5a688004267
Author: Paul Smith <psmith@gnu.org>

    Include <strings.h> globally
    
    Various code uses str{,n}casecmp() so include <strings.h>, if it
    exists, everywhere.
    
    * configure.ac: Check for <strings.h> explicitly.
    * src/makeint.h: Include it if HAVE_STRINGS_H, for str{,n}casecmp().
    * src/job.c: Remove include of <strings.h>.
    * src/main.c: Ditto.

Author: Paul Smith <psmith@gnu.org>
Date:   Sat Jan 7 22:01:19 2023 -0500

    * gl/lib/glob.c: Don't try to support _LIBC, don't use __stat()
