win32-vc90 build crash for "none://localhost:34532" if ProxyOverride in registry is not equal to "<local>"

What steps will reproduce the problem?
1. Specify at least one proxy exception url via IE settings
2. Run meld 3.11 with python2.7 and 
http://sourceforge.net/projects/pygobjectwin32/files/

What is the expected output? What do you see instead?
meld crashed in _close function called form libproxy.dll

What version of the product are you using? On what operating system?
libproxy 0.4.11, windows 7 x64, built in release configuration with vc90 
toolset.

Please provide any additional information below.

The crash appears because sockets on windows must be closed by closesocket 
function, not _close.

Attached patch fixes problem to me.
