Dear Ipopt-Team,

I was wondering if you would be so kind and help me with the following 

I have Windows 2000 available with a Compaq Digital Fortran 6 and 
Microsoft Visual C++ 6.0 compiler. Furthermore, I have the current 
Cygwin environment with gcc and g77 and other necessary tools.

What I would like to do is to produce a static Ipopt library that I can 
compile and link with Fortran code using Digital Fortran 6 in a pure 
Windows environment (actually, I want to produce a static Dfo library 
for Windows). Now, I learned from previous postings that compiling the 
Ipopt Fortran and C sources with Digital Fortran and Visual C++ manually 
won't work for some reasons.

On the other hand, it was no problem to produce the libipopt.a library 
in the Cygwin environment with the gnu compiler and the -mno-cygwin 
option. However, I don't know how to convert the .a library into a .lib 
library that I can link with Digital Fortran object files. Is there a 
way to accomplish that?

The second question is, I have the precompiled Intel MKL 7.0 for Windows 
libraries available, is there any possibility to include these instead 
of the reference implementations when using the Cygwin environment?

Hopefully my questions are not beyond the scope of this mailing list. 
Thanks a lot and best regards,
