I have contact some guys from HP, unofficial reply is if it's not
documented it's not supported... Why it's defined in socket.h may be
because the TCP/IP stack from HP on OpenVMS is a port of the Tru64 Unix
stack and the flag was present in Tru64.
We will also investigate if the behaviour on OpenVMS when you use
MSG_WAITALL is broken or not.

So I will, in a forthcoming kit don't export this symbol under OpenVMS
(if it's not documented it's not supported).
I have also take a look at the problem of using big recv() buffer and
found a bug when the buffer size is > 32767, only the first 32767 bytes
are read, this will be also fixed in the next kit (only Python 2.5).

I expect to have a new kit which include all these fixes be available
before the end of the week.
