+ngIRCd release 15 has successfully been tested on Microsoft Windows XP
+Professional using the Services for UNIX (SFU) version 3.5 and Microsoft
+Windows 7 with the bundled Subsystem for UNIX Applications (SUA).
+
+SFU are supported on Windows 2000, Windows 2000 Server, Windows XP, and
+Windows Server 2003. SUA is supported on Windows Server 2003 R2, Windows
+Server 2008 & 2008 R2, Windows Vista, and Windows 7 -- so ngIRCd should be
+able to run on all of these platforms.
+
+But please note that the poll() API function is not fully implemented by
+SFU/SUA and therefore can't be used by ngIRCd -- which normally would be
+the default. Please see <http://www.suacommunity.com/faqs.aspx> section
+4.25 for details:
+
+  "If you do try to use the poll() API your program will block on the
+  API call forever. You must direct your program to build using the
+  select() API."
+
+So when running the ./configure script, you HAVE TO DISABLE poll() support:
+
+  ./configure --without-poll
+
+ngIRCd then defaults to using the select() API function which works fine.
