Going only by that information, I'd guess that the qt developers
encountered some problem, and decided to use an oddball feature
of ar in a way that's different from its "only purpose", and which
doesn't support the environment-variable substitution you want.

As far as I can tell, MRI is Microtec Research, Inc., a producer
of embedded-systems tools. There might be little interest in
turning ar's MRI hack into a general-purpose scripting facility.

I don't find any string in the MSYS ar binary that would print
the message quoted. I know I've used ar command lines longer
than 255 characters. I wonder whether the qt people diagnosed
the problem correctly.

If you transform the generated script into a command line, does
ar execute it correctly?
