+describing how he

+<MENU>
+<LI> Install MinGW and Msys.  This gives a mini GNU-like compile environment 
+that produces Windows-compatible results.
+<LI> You may need to configure and build in Windows "Safe mode".  Try 
+./configure in normal mode; if it dies with "fork" problems, use Safe mode.
+<LI> Edit the "configure" file.<BR>
+ after this line:<BR>
+     <CODE>DEFS=-DHAVE_CONFIG_H</CODE><BR>

+If you
 desire to build directly using Visual Studio or other non-Unix-based
 environment, you will need to derive the necessary information from the
 supplied Makefiles.
