    https://github.com/GitCredentialManager/git-credential-manager/issues/576

    Fix some problems such as:

    1) If output of non-cygwin app and input of cygwin app are connected
    by a pipe, Ctrl-C has to be sent twice to stop apps when the
    cygwin app does not read stdin at the moment.
    2) In cmd.exe started from cygwin shell, if output of non-cygwin
    app and input of cygwin app are connected by a pipe, Ctrl-C
    can never terminate the apps.
    Fix exit code when non-cygwin app is terminated by Ctrl-C.
    Fix a bug that the order of the console key inputs are occasionally
    swapped, especially when CPU load is high.
    Addresses: https://cygwin.com/pipermail/cygwin/2022-February/250957.html
    Fix a problem that fsync() flushes the console input buffer unlike
    linux. fsync() should return EINVAL for special files such as tty.

    Fix a formatting problem in gmondump where all displayed addresses are
    mistakenly prefixed with "0x0x". Fix man pages for gmondump and ssp.

    This is a bugfix release.
