Merging issue67 also resolved this issue.

A bit off topic but if mingw support is a matter I just discovered that builds 
of osi and coinutils are available on OBS 
https://build.opensuse.org/project/show/windows:mingw:win32

The documentation is on the wiki (visible for our group only), and the
announcement is deferred until we have full windows support.

Merged and pushed. Thanks for your work, Patrick!

What is still missing is the documentation and announcement. Silvan, can you work 
together with Patrick on this, please?

After this has been merged, we need to document and announce the new MSVC 
support.

Patrick is looking into how to build OSI with MSVC on Windows. Also, we agreed 
that to add a local windows.h file to avoid command line compilation flags. Apart 
from that, the patch looks could to me.

I am now at a stage with the windows buildbot where I would need to be able to
build the Fast Downward master with MSVC (issue480). What is the standing with
this issue here? I haven't followed all the discussions at bitbucket, but it
seemed that the functionality is given and that the only missing part is about
how to integrate it.

I have started to look on the portability of fast downward.
Until now the code changes where only minor.

Currently there is an issue with the Parser. You might have a look on the 
comments at https://bitbucket.org/TheOneRing/hg.fast-downward.org/pull-
request/12/investigate-msvc-support/diff
