I suspect that FIOCLEX and FIONCLEX are not defined at all on cygwin.

On BSD they are defined on sys/filio.h as

  #define FIOCLEX         _IO('f', 1)
  #define FIONCLEX        _IO('f', 2)

see  http://fxr.watson.org/fxr/ident?im=10;i=FIOCLEX


While on Linux they are defined or
  #define FIOCLEX         _IO('f', 1)
  #define FIONCLEX        _IO('f', 2)
or
  #define FIONCLEX        0x5450
  #define FIOCLEX         0x5451

see http://lxr.free-electrons.com/ident?i=FIOCLEX
