[Ipopt] building shared libraries under mingw doesnt work for me

[Andreas Waechter]

Hi Jens,

binaries for the Ipopt project are here:

http://www.coin-or.org/download/binary/Ipopt/

(There is a link to this from the Ipopt mailing list).  The DLLs are in 
the Ipopt-*-win[32|64]-dll.zip files.

Regards

Andreas
