Thanks for the link. I wasn't aware of the existence of such a page.

I don't really like the proposed solution. The problem is not the fact 
that they are Windows directories, but that they contain spaces.

A better way would be to call OpenWRT Make with a Linux-only path like:

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin make

instead of modifying a global WSL setting.

BTW. As far as I could find, spaces are legal in $PATH, so I would say 
that there are bugs in OpenWRT regarding handling paths with spaces.

Thanks again,

Bas.
