Most likely, the issue is related to the Cygwin make command, which is buggy. See the solution here:<div><br></div><div><a href="https://projects.coin-or.org/BuildTools/wiki/current-issues#CurrentIssues">https://projects.coin-or.org/BuildTools/wiki/current-issues#CurrentIssues</a> </div>

<br>
<br><font face="sans-serif">During "make test", we get:</font>

<br><font face="sans-serif"> .deps/OsiAuxInfo.Plo:1:

<br><font face="sans-serif">For comparison, I just did the build
in a more conventional Linux environment (a VMWare emulation, in this case,
but I don't think that matters), and got through "make test"
with no errors. By the way, the set of compiler warnings I get during
build is slightly different in the two environments.</font>
<br>
<br><font face="sans-serif">So, it seems that there is something
about our Cygwin configuration that wasn't anticipated by the COIN build
tools: does anyone have additional insight?</font><br>_______________________________________________<br>
