  <li><b>Windows Only:</b> The shell invoked by gmake, <code>shmsdos.exe</code>, is likely to crash when invoking some Java tools on Windows. The current workaround is to use some other shell in place of <code>shmsdos</code>, such as <code>sh.exe</code>, which should be distributed with the <a href="http://sourceware.cygnus.com/cygwin/download.html">Cygnus toolkit</a> you installed to build NSS. The change is unfortunately rather drastic: to trick gmake, you rename the shell program.

   Making this change will probably break other builds you are  making on the same machine. You may need to switch the shell back and forthdepending on which product you are building. We will try to provide a moreconvenient solution in the future. If you have the MKS toolkit installed,  the &lt;tt&gt;sh.exe&lt;/tt&gt; that comes with this toolkit can be used as well.</li>
