f2c is recommended because it seemed to be the only non-commercial way
on Windows. But it does not work with Fortran90 code (like Mumps).
People also had success with gfortran on Windows recently, so that could
Intel Fortran works too.

Best is when you just replace the Ipopt directory in Bonmin 1.0.1 with
the one from Ipopt 3.5.5. That should work.
On the other hand, the changes in Ipopt that are not in the one used by
Bonmin 1.0.1 might be neglectable. Probably there will be a Bonmin 1.0.2
some day.
Or you just use Bonmin 1.0 (from the stable branch).
