Any possibility to support this?

There is no upcoming plan to support and it would require extensible work
to port glibc to run on Windows.  Afaik MinGW-w64 uses MSVCRT library 
(which is part of the Windows Kits provided by Microsoft itself) and you
can integrate some missing POSIX facilities with gnulib.
