Please study the code a little closer:
process.c and sysdep.c use O_NONBLOCK / O_NDELAY in general for
non-blocking sockets.
They use FIONBIO only for very specific platforms, and typically
only in relation to PTYs.
So O_NONBLOCK is the right choice for the generic code.
However, w32.c seems to use FIONBIO consistently to handle "O_NDELAY".
I'm not familiar with the code to say what's going on.
