For clarity, it may be better to just ifdef the WSA startup routine 
separately.

I think gnustep-base forgo compatibility with Windows 9x/Me anyway so 
the lack of good poll support may not be such a problem, especially 
considering the NT series of kernels offer much better IMHO 
pipe/IPC/threading/Unicode semantics than their 9x counterparts, 
although still complex implementations and not compatible with Unix to 
any major extent. Thankfully Win32 sockets are based on BSD's 
implementation. Also, 9x/Me are no longer supported patch-wise by 
Microsoft, so we shouldn't feel that obliged to support them fully.
