[ squint... ]  They define IPV6_V6ONLY and AF_INET6 but not
IPPROTO_IPV6?  That's pretty bizarre.  You might want to hunt around in
the system header files for those symbols and see if there's some
feature macro or something we need to set to get IPPROTO_IPV6 to be
defined.  Or maybe it's in some other header file that we're not
including.

I know neither Magnus or I have tried yet, and I doubt any of the
other hackers have either.

Unfortunately I had to uninstall VS2005 to install VS2008 due to limited
space, or I'd search the old libraries to see where the symbol used to
be. Anyone care to search their VS2005 includes for IPPROTO_IPV6 so I
can compare to the VS2008?

Also, following the usual build procedure (using build.bat/build.pl), I
encountered errors saying I needed to do "vcbuild /upgrade" on
postgres.vcproj, libpgport.vcproj, and pgevent.vcproj. After consulting
with one of our QA people who builds stuff in Windows all the time, I
came up with the following procedure to build postgres under VS2008
(This includes changing pqcomm.c per Tom's comment below):

(in msvc)
mkvcbuild.pl
cd ..\..\..
vcbuild /upgrade postgres.vcproj
vcbuild /upgrade libpgport.vcproj
vcbuild /upgrade pgevent.vcproj
(actually, I wound up creating a script that did vcbuild /upgrade to ALL
of the vcproj files here)
msbuild pgsql.sln

Note that after doing all the vcbuild /upgrade commands, I used msbuild
referencing the pgsql.sln file instead of vcbuild to do the actual
build. So, aside from the issue of the missing IPPROTO_IPV6 symbol, its
built under VS2008. It will probably be some time before I can try
running postgres built this way, as we're under the gun to get a release
out this week.

I'm not an MS developer by any means, so if someone has a better way to
do this feel free to say so. This is what worked for me.

No idea, I don't use MSVC.

Well, you could just change

#ifdef IPV6_V6ONLY

to

#if defined(IPPROTO_IPV6) && defined(IPV6_V6ONLY)

and then it would compile --- but whether it would work right is less
clear, unless your machine doesn't do IPV6 anyway.  Since we know this
code compiles under VS2005, I'm inclined to recommend that you look
for the real solution, which is to find out where that symbol went...

It is defined unconditionally in PlatformSDK/Include/WinSock2.h
in VS2005 Professional.

Will a build run on Win2000 if we define 0x0501 ?

I believe it will - as long as we don't use any of those features. And
AFAIK the API calls for winsock hasn't changed - it's just what
parameters they take. But it is certainly something w need to verify
by testing :-)
