We should use O_NONBLOCK. It is more widespread on Unix nowdays, and

It is compatible with Windows?
I don't know. Why is it important? We should do the right thing for each
platform.
How do we hande this elsewhere in Emacs?
src/process.c, src/sysdep.c and src/w32.c already use FIONBIO.
process.c only uses FIONBIO in one place and only on STRIDE, but O_NONBLOCK is
used many times.
sysdep.c also uses it in one place, this really should be O_NONBLOCK instead.
w32.c is MS Windows specific, so it does not count.
Something like this would handle all cases:
#ifdef O_NONBLOCK
/* Use O_NONBLOCK. */
#else
#ifdef O_NDELAY
/* Use O_NDELAY */
#else
/* Use FIONBIO */
#endif
#endif
