Sorry, I'm not being clear.  You need to define FD_SETSIZE _before_
including winsock.h/winsock2.h.  This constant defines the size of the
fd_set type used for all calls to select() and the FD_CLR/FD_SET/etc.
macros in a specific source file.

The simplest is to define this externally, in the MSVC project file,
as a macro definition that gets passed to all source files regardless.
