I think more than 1 job with make now works on a recent MSYS2. To be 
honest I cannot remember if it is working. For a long time MSYS 
(MinGW32) had problems.

Yes but indirectly. For example 
You could add __ln_s to as 'cp' to see if it works. I seem to 
remember from the distance past that MSYS basically did a copy rather 
than create an unsupported link.

Also the RSB cannot control the contents of a tar file is expands and a 
tar file can contain a symlink. The same goes for a build system 
contained in a package.
