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

[Peter Carbonetto]

I have a couple suggestions:

  * Try compiling IPOPT first *without* the MATLAB interface. 

  * Some people have already given some useful tips on compiling IPOPT on 
    Windows. There has been some recent suggestions for the MATLAB 
    interface in particular. Please search the archives of the IPOPT 
    mailing list.
