I had to change the shebang in mingw64/bin/scons to use python3: #!/mingw64/bin/python3
instead of #!/usr/bin/env python. With this change, scons --version tells that it it 3.0.3.
Now, actually running scons fails- it seems unable to import site tools from my (local= site_scons\site_tools:

The 'tool 'gcc_x68' and its init does exist, in fact the whole thing works fine when using MSYS2/python2 and the pacman SCons package, The reason I would like to not use this is a massive performance problem of Py2 when walking dir's. In MSYS2, Py2 can't really benefit from scandir because MSYS2's Py2 patches sys.platform to 'msys', making scandir's optimization not appliable. Moreover, we would like to migrate to Py3, in fact Py2 is around only due to MSYS2 seems to require Py2. All our other stuff is already for Py3.

I'm not sure what is going wrong here, googling this gives e.g. http://scons.1086193.n5.nabble.com/Python-3-issue-td41665.html , but this is inconclusive to me.
Is there anyone who knows what to do in order to get scons running under mingw64?
Thx in advance
