Обсуждение: Two very minor win32 patches

For src/backend/postmaster/postmaster.c and src/include/c.h
(Note: should ioctlsocket_ret be initialized to 1 for BEOS too, and can it
take an unsigned parameter? If so, could simplify.)

OK, I have updated this for 7.4 and CVS.  Any idea why it has to be
initialized to 1 and not 0?

Never mind --- I figured it out:

FIONBIO
    The argp parameter is a pointer to an unsigned long value. Set argp
to a nonzero value if the nonblocking mode should be enabled, or zero if
the nonblocking mode should be disabled. When a socket is created, it
operates in blocking mode by default (nonblocking mode is disabled).
This is consistent with BSD sockets.

    argp value     Nonblocking mode

    0     Disabled
    nonzero     Enabled
