         NuttX uses the GCC compiler's <code>-M</code> option to generate make dependencies.  These
         dependencies are retained in files called <code>Make.deps</code> throughout the system.
         For compilers other than GCC, there is no support for making dependencies in this way.
-        For Windows native GCC compilers, the generated dependencies are windows paths and not
-        directly usable in the Cygwin make.  By default, dependencies are suppressed for these
