    gio tool: Fix build on Windows/non-GCC
    
    The recently-added GIO tools is intended to be built on all platforms, so
    adjust the code a bit to enable this:
    
    -Use gssize instead of ssize_t, as ssize_t is not supported by all
     compilers.
    -Include io.h on Windows, and define STDIN_FILENO and STDOUT_FILENO if
     necessary on Windows.
