I notice this from win32 setup.py bdist_wininst --plat-name=win-amd64

> running bdist_wininst

followed by errors related to a missing library (the amd64 version won't work with a win32 build).

I do have the x86_amd64 stuff installed and after applying a patch to fix another small cross compile error I do see a proper build ie

setup.py build --plat-name=win-amd64

and then use

setup.py bdist_wininst --plat-name=win-amd64 --skip-build 

does work. I believe that bdist_wininst is wrongly relying on build to get the right plat_name, but that isn't happening.

The attached patch seems to make things work for me by forcing plat_name down from the top
