Cygwin code that I sync with source ware and then merge into MSYS branch. I
create git repository on MSYS2.sf.net only today and do not have time yet
to set it properly.
Therefore the binary package infringes the Cygwin license, or, more

IRC. It would be more right way I think but I think you don't interesting
in it. I'm right? That is why I create fork of Cygwin. But if it possible
to support MSYS mode in Cygwin sources I think all be happy to not create
many forks an so on.
