Why is <fenv.h> not available in cygwin?

[Roberto Bagnara]

I am wondering why this header file and the corresponding C99
functionality appears to be missing from cygwin.
Does anyone know?
Cheers,

     Roberto

P.S. I know fenv.h is available in mingw, but this does not
      help me as I cannot then link with libmingwex.
