>         Enables automatic dependency tracking.  With this option, the
         makefiles are set up so that all affected object files will
         be rebuilt when any header file is changed.  This is useful
         if you are doing development work, but is just wasted overhead
         if you intend only to compile once and install.  At present,
         this option only works with GCC.
