Jay Francis 5dfde4709d Applies more patches for Windows compiling 
Missed the 0001 and 0002 patches provided by N1AI (https://github.com/n1ai)
Patch 0003 adds some items that are later removed, so that patch is deliberately ignored.

Part of the confusion is the conda-forge recipe was forked from N1AI and not the upstream
repo.
