That discussion is full of misinformation, so let's ignore it, OK?

I cannot reproduce this.  in general, Make on Windows uses APIs that
support command lines up to 32K bytes.  I just successfully ran a
Makefile that invoked a command with 23K bytes (which is more than
your 18K, as reported on Stackoverflow), with no problems.

So I think some other factor is at work here.  The first suspect is
the way you built Make 4.2.  Could you please try the binaries
available from this site:

  https://sourceforge.net/projects/ezwinports/files/?source=navbar

(I'm guessing you don't need Guile support in Make, so the
"without-guile" binary zip is for you.)  This is the binary I used in
the experiment described above.  The command line I tried was this:

  echo 123456789 123456789 123456789 123456789 123456789 ...

etc., up to 23K characters.  Also, since you seem to be using the MSYS
Bash, I used it as well (I have MSYS installed here).  I don't know
what kind of Bash build you got from the QNX toolkit, but at least the
output of "sh --help" I get here is identical to what you show, so
there's hope it's the same or similar binary.

So please try the above-mentioned binary distribution of Make 4.2, and
please try the simple command I used.  If that works, then I suggest
to try your real target with the same binary of Make.
