Release 1.2 2024-07-04

Fixed txzchk(1) for BSD (in particular NetBSD) by #include <sys/wait.h>.
Thanks to @SirWumpus for the report!

Changed txzchk TXZCHK_VERSION"1.0.3 2024-03-02" to"1.0.6 2024-06-25".

Updated bug_report.sh script with new option -m make to specify path to
make(1). The script now also tries to find gmake, first and if that fails
it will look for make. In the case that it is not a regular executable file it
is considered a command line error along the lines of 'command not found'. This
helps simplify the handling of the error codes as without make(1) the script
is essentially useless anyway (or mostly useless).

Changed bug_report.sh BUG_REPORT_VERSION from "1.0.3 2024-06-26""
to "1.0.4 2024-06-26"`. Man page updated for these changes.

Fixed bugs that prevented NetBSD from compiling this code. Fixed
a number of compiler warnings under NetBSD. Thanks to @SirWumpus
for the detailed bug report and his assistance in testing.

Fixed a bug that caused iocccsize(1) to crash on some systems, such
as MacOS under Apple Silicon, when given a binary blob such as the
iocccsize binary as input.

Changed iocccsize IOCCCSIZE_VERSION from "28.14 2024-01-04"
to "28.15 2024-06-27".

Updated Makefile.example to be more like IOCCC winning entry Makefiles.

Expanded remarks.example.md to include more information about
IOCCC markdown guidelines as well as more consistent with the new
IOCCC submission process.

Improve the Makefile to allow for NetBSD to run make prep,
make slow_prep and make release.

Changed test_ioccc/prep.sh PREP_VERSION from "1.0.1 2024-03-02"
to "1.0.2 2024-07-03".

Disabled parallel make for most of the repo.

Updated .github/workflows/codeql.yml to use up to date actions for
checkout, node setup, Initialize CodeQL, Autobuild, and Perform CodeQL Analysis.

Added .github/workflows/test.yml to perform make actions such as
make slow_prep and make test as part of the GitHub workflow.

Fix .github/dependabot.yml to set an update schedule for GitHub Actions.

Changed MKIOCCCENTRY_REPO_VERSION from "1.1 2024-05-19"
to "1.2 2024-07-04".
