    Hack to restore "configure --enable-x11" on macOS â?¥ 11
    
    Since macOS 11, configure --enable-x11 (and the equivalent with CMake)
    fails when compiling fl_write_png.cxx in parsing of time.h.
    The error happens only if png.h is included without time.h having
    been included before.
    The fix is to #include time.h before png.h
    
    A better fix than his hack is desirable.
