I occasionally contribute to mingw-w64 repository. Is there anything I can
do so that cygwin uses latest headers and libraries from mingw-w64?

To Takashi Yano:

> Then, is it possible to DuplicateHandle() for three handles in HPCON to
other process which calls ioctl() with new HPCON?

** THE FOLLOWING PROCEDURE USES UNDOCUMENTED AND UNSTABLE CODE **

To use HPCON in another process, first cast it to a pointer of struct of
three handles as below:

    struct HPCON_INTERNAL {
        HANDLE hWritePipe;
        HANDLE hConDrvReference;
        HANDLE hConHostProcess;
    };

    HPCON hpCon;
    HRESULT hRes = CreatePseudoConsole(consoleSize, hPipePTYIn,
hPipePTYOut, 0, &hpCon);
    HPCON_INTERNAL *hpConInt = hpCon;

Then **inherit** and use hpConInt->hWritePipe to write the resize signal.
Get detail information about that buffer here[1]. Sample in my repo[2].
