xterm 368 and mintty 3.5.1 implement a new feature to support
notification of terminal scaling via font zooming also if the terminal
text dimensions (rows/columns) stay unchanged, using ioctl(TIOCSWINSZ),
raising SIGWINCH.
This does not work in cygwin currently. The attached patch fixes that.

xterm 368 and mintty 3.5.1 implement a new feature to support
notification of terminal scaling via font zooming also if the terminal

ioctl(TIOCSWINSZ), raising SIGWINCH;
this patches cygwin to support that scenario
