fnctl nonblocking still blocking

Hi,
   I am working on porting Squid to
cygwin, I posted before about a problem with accept() stopping on the second
call to it.
ÂÂ
I have tracked it down to the socket still blocking
on io when there is no pending connection, even though the earlier call to fnctl
was successful.
ÂÂ
The call made is (fcntl(fd, F_SETFL, flags |
SQUID_NONBLOCK) < 0),
where flags was retrieved by a prior call to
F_GETFL, and SQUID_NONBLOCK is #defined to be
O_NONBLOCK, I have also tried O_NDELAY with the same results.
ÂÂ
My question(s) are:
what is the official status of non-blocking
accept() calls in cygwin 1.1.2?
where in the winsup source is fcntl implemented? I
found a call to _fcntl but could find where that has been implemented to follow
through...
ÂÂ
cygcheck -s -v -r attached
ÂÂ
Thanks in advance,
Rob
