Despite a few non-portability issues in the testsuite and a few unsupported features, it looks like cygwin is in pretty good shape!</SPAN></FONT></DIV><DIV><FONT class="Apple-style-span" face="Monaco" size="2"><SPAN class="Apple-style-span" style="font-size: 10px;"><BR class="khtml-block-placeholder"></SPAN></FONT></DIV><DIV><FONT class="Apple-style-span" face="Monaco" size="2"><SPAN class="Apple-style-span" style="font-size: 10px;">-Chris</SPAN></FONT></DIV></BODY></HTML>
