[Ipopt] After compiling Ipopt with Cygwin "make test" fails

[Stefan Vigerske]

Hi,

I can reproduce this on cygwin with gcc 4.3.2

The problem seem to be the -lcygwin here. When I link hs071_c.exe
without the -lcygwin, then it works fine.
I don't know how it get in there, I extra compiled with
--enable-doscompile, but gfortran seem to tell configure that it wants
to have it.

So I guess you can just ignore this failure, and when you like your own
application with the Ipopt lib, don't link against cygwin.
