Msys2 on Windows 10

[Jeff Mayes]

Hi
I have a fresh install of Windows 10, with updates.  Then installed MSYS2 as instructed here:
https://docs.rtems.org/branches/master/user/hosts/windows.html#msys2

Fetched the RSB, and then tried to build rtems-sparc tools, like this...

$ ../source-builder/sb-set-builder --prefix=/home/mayes/dev/rtems/5 5/rtems-sparc

This happens when using Python3 and also when using Python2.
Any ideas?

Thanks
Jeff
