Can you report the relevant section from config.log where
configure disables sockets?

Attaching the whole log just in case :-)

Please retry, checking the checkbox.

Sorry.
Hope it's OK now.

Got the file in email now; 290k is too large for an SF
attachment.

However, I still cannot find out what you mean by
"./configure disables socket module". What message that you
got are you referring to, and what specifically did you do
to "add it manually"?

When running "./configure --prefix=/usr" python is built OK,
but socketmodule (_socket.dll) is not build.
There is no message on that.

By "adding manually" I mean uncommeting the socketmodule
line in Modules/Setup and then running "make".
Then the build system tries to build socketmodule and fails
with the above error.

I get exactly the same results as tebeka, FWIW.

(make works fine, but doesn't build the module, then
uncommenting the line gives the above error).

The getaddrinfo.c errors seem to be similar to those I
reported in bpo-991125. (A required header file which resides in
the same directory as getaddrinfo.c is in an #if 0 block. Fix
that and getaddrinfo.c builds correctly).

Fixed compilation errors with the attached patch.

BTW, the socket module builds automatically for me --
there was no need to manually edit Modules/Setup.
