[OS] Another data point for OS / ASL under Msys / cl

[Robert Fourer]

Kipp, Lou, Jun,

If ASL support is dropped, what do we lose?  Is there a way ASL can still be
made available, but without some of the desirable features of COIN-OR's
project setup?

Dave Gay provided a fix yesterday to a problem with ASL that was preventing
compilation of the AMPL/KNITRO interface.  So there is a possibility that he
can provide some insight here, although he is not familiar with specifics of
the COIN-OR setup.

I forwarded your question that partly involved KNITRO,

and got the following response from Todd Plantenga:

Does this make any sense?
