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

To answer the first question, I think the OS project loses a lot without 
ASL. Without ASL we can't do any processing of nl files or use 
amplClient.  I think the answer to the  second question above is no. 
Right now you really do build ASL "separately" from the COIN projects 
and that is causing the problem. For example, the COIN-OR BuildTools 
configure script is used to build the COIN-OR project Makefiles but ASL 
is built with the Makefiles that it downloads with -- there is no 
coordination. So I see the problem as ASL not being part of the COIN-OR 
project setup.  If it were, then when we use the debug option for the 
COIN-OR configure script the debug option would get put into the ASL 
Makefile. That does not happen now.

Not really. When I build the OS project using --enable-debug with Knitro 
I get the crash described in the previous email I sent to you. When I 
build the OS project again using --enable-debug without Knitro 
everything compiles, links, and passes the unitTest. So it would seem 
Knitro causes the problem since there is no problem when the project 
builds without Knitro. I will investigate further.
