- win/cygwin support revived, for now no ipv6, no tcp (relies on fd passing

 between processes which is not yet supported under cygwin), no dynamic
 modules, only statically linking (backlinking is not supported under windows
  and possible workarounds are too work intensive)

+ Cygwin  (alpha state, partial support)

+ make sure make, bison, flex, minires and minires-devel (needed for the resolver functions) are installed.

+ Only building ser's core and some static modules is supported for now.
+ Stuff known not to work:
+           - IPv6 (cygwin doesn't support it yet)
+           - TCP (the tcp code heavily depends on file descriptor passing 
+             between processes, which is not yet supported by cygwin)
+           - dynamic modules (non statically linked -- not supported because
+             backlinking doesn't work in windows by design)
