Redefining compiler constants is bad bandaid. A similar bandaid was in
place to begin with caused this problem. If you believe PostgreSQL will
never use code that needs the true errno value then go ahead with Option 1.

After looking over the changes it was a merge mistake. I originally
wrote the patch on the 9.2 branch and ported it to master. Nothing to
call "misguided".

Just so that everyone understands: I was looking for comments to discuss
a solution to the socket error checking problem. I'm not looking to
shove anything down one's throat.
