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

[Stefan Vigerske]

Hi,

I have no experience with the matlab interface.
The error you see probably comes from an inclusion of windows.h somewhere.
windows.h just defines "short"  (very very dumb), and that often makes
problems.
Somewhere behind an  "#include <windows.h>" should be an '#undef short"
included.
