+      I've never tried this one, but I off the following reported by an ez80 user using the ZiLOG ZDS-II Windows-native toolchain:
+    </p>
+    <blockquote>
+      <p>
+         &quot;I've installed ZDS-II 5.1.1 (IDE for ez80-based boards) on wine (windows emulator for UNIX) and to my surprise, not many changes were needed to make SVN snapshot of Nuttx buildable...
+         I've tried nsh profile and build process completed successfully.
+         One remark is necessary: Nuttx makefiles for ez80 are referencing <code>cygpath</code> utility.
+         Wine provides similar thing called <code>winepath</code> which is compatible and offers compatible syntax.
+         To use that, <code>winepath</code> (which itself is a shell script) has to be copied as <code>cygpath</code> somewhere in <code>$PATH</code>, and edited as in following patch:
+       </p>
+       <ul><pre>
+# diff -u `which winepath` `which cygpath`
+--- /usr/bin/winepath 2011-05-02 16:00:40.000000000 +0200

+</pre></ul>
+      <p>
+        &quot;Better solution would be replacing all <code>cygpath</code> references in  <code>Makefiles </code> with  <code>$(CONVPATH)</code> (or  <code>${CONVPATH}</code> in shell scripts) and setting <code>CONVPATH</code> to  <code>cygpath</code> or  <code>winepath</code> regarding to currently used environment.
