+        <b>Dependencies</b>
+        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 surpressed for these
+        compilers as well.
+      </li>
+      <p><small>
+        NOTE: dependencies are suppress by setting the make variable <code>MKDEPS</code> to point
+        to the do-nothing dependency script, <code>tools/mknulldeps.sh</code>.
+        Dependencies can be enabled for the Windows native GCC compilers by setting
+        <code>MKDEPS</code> to point to <code>$(TOPDIR)/tools/mkdeps.sh --winpaths $(TOPDIR)</code>.
