[TUHS] Another awk version is now available

[Aharon Robbins via TUHS]

If anyone wants to have Yet Another Awk Version available for their
testing: https://github.com/arnoldrobbins/mksawk

This awk was originally written by Mortice Kern Systems in the 80s
sometime. Solaris adopted it for their POSIX awk, and it was released
with OpenSolaris.

I took this code from Illumos and made the minimal changes to get it
to build without errors. It passes a "hello, world" smoke test,
including handling Unicode multibyte characters.

I'll probably arrange to announce this on comp.lang.awk sometime soon.

I originally did this like in 2006, and decided to start over with
the current code before publishing it on github.
