QNX

===

   (This section was graciously brought to us by David Bentham)

   By setting FD_SETSIZE early in connect.c we override the QNX default value

   and thus avoid a crash.

   Fortunately in the QNX headers its defined as

    #ifndef FD_SETSIZE

      #define FD_SETSIZE 32

    #endif

   so its relatively easy to override without changing the original

   definition. QNX claim posix compliance so this definition style could be

   standard in other o/s's. Eg Microsoft Visual C++ 6 defines it similarly,

   but its set to 64.
