If you are talking about the resizing of, say, the standard Windows
console window that Cygwin runs in by default then that is,
unfortunately, a limitation in Cygwin's implementation of SIGWINCH that
is probably not going to change.
It should work much better when running in rxvt, mintty, or xterm
though.
