is the same: a Bad Address.

The -DNON_TRANSITIVE=ON option removes lots of the -L and -l options,
but still leaves lots of -I options (which we treat in a transitive
way only) so we are still stuck with that pretty long (1200+ bytes)
line length.

It's an extremely interesting result, however, that
-DNON_TRANSITIVE=ON appears to work (got just as far into the test
before finding this Bad Address error) as well as
-DNON_TRANSITIVE=OFF.  So once you get completely through the comprehensive
script without issues on MinGW-w64/MSYS2 with -DNON_TRANSITIVE=ON, I
will make -DNON_TRANSITIVE=ON the default on that platform, and the
same with Cygwin.

By the way, when carefully checking the above results, it appears you
do not have either git.exe or diff.exe installed on MinGW-w64/MSYS2.
The git.exe application is needed to help the comprehensive test
script figure out what PLplot commit you are testing (and might also
be generally useful to you).  The diff.exe application is of
more fundamental concern since it is what is used to determine
the important PostScript difference report.

I am not completely sure whether you should install the
"mingw-w64-x86_64" version or the "msys" version of these packages,
but since they are used primarily in a bash environment, I suggest you
try installing the msys versions first to see how they work.  In that
case, the names of the relevant packages are "git" and "diffutils".  I
also mentioned before you were missing the Qt package.  I would try
installing the mingw-w64-x86_64 version of qt4 first since Qt4 is a
higher quality library than Qt5 right now, but if that leads to
conflicts, try the mingw-w64-x86_64 version of qt5 instead.

I look forward to the results from those simple tests which should be
quite informative.
