"couldn't make stderr distinct from stdout" when running Cygwin commands

>SOLUTION

Check you envvars.

Originally the Path had Git's bin before cygwin64.
  Path=..;C:\Git\bin;C:\cygwin64\bin

Switching places:
  Path=..;C:\cygwin64\bin;C:\Git\bin
in order to read cygwin's library first.

In such case, you may get issues with git. So test it after your have changed the Path.

If it happens to get problems with Git, it's necessary to point git's executables manually or using a script to set the local envvar during git's execution context.

Another solution could be adopting one or another.
