+Recent development is with GNU/Linux. I have tested compilation on
+FreeBSD v4.0, BSD/OS v3.0, and Solaris v8 (gcc 32-bit), and IA64 (gcc)
+, and Microsoft Windows 2000 (Visual C++ 6.0 and cygwin).
+
+Microsoft Windows Installation
+------------------------------
+Run make.bat from the root directory
+
+CYGWIN v1.1.0
+-------------
+The file /usr/i686-pc-wygwin/include/cygwin/in.h has a bug. The line
+ struct in_addr6 sin6_addr;
+should be deleted.
+getopt_long appears broken, configure.in checks for cygwin to use
+bundled version of getopt_long.
