    console.cpp: Make code build on Windows
    
    The new code that tries to detect Ctrl+C almost built fine on Windows,
    except that Windows does not have sigjmp_buf, siglongjmp() and
    sigsetjmp().  For Windows we have near-equivilents jmp_buf, longjmp()
    and setjmp(), so use them.  The mask parameter for sigsetgmp() does
    not apply on Windows, so just discard it when calling setjmp() in its
    place.
