As an alternative to Cygwin, you could try msys2 / mingw-64.  My
experience is that this can often be a lot faster than Cygwin, and
creates stand-alone programs that feel less "alien" in Windows.
However, it has limitations if you need more accurate POSIX emulation,
such as for fork() calls.  It's worth trying.

You could also install VirtualBox and run the Linux system within a
virtual machine, on the Windows host, if you can't escape from using
Windows on the actual PC.
