[erlang-patches] patch: updated windows build documentation

[Dave Cottlehuber]

This patch updates the Windows build docs, to note newer versions of
dependencies that work, & also how to compile with the free Microsoft
Visual Studio 2008 C++ Express compiler.

- using latest free VS2008 compiler & SDK 7.0
- compiling wxWidgets to compile with newer MS tools via command line
- latest tested versions of OpenSSL + wxWidgets

git fetch git://github.com/dch/otp.git updated_INSTALL-WIN32.md

I ended up scrapping the old branch both in remote & my repo, here's a
new clean patch + 80 char wrapped.
Thanks Tuncer for "gitting" it all sorted out.

cheers
Dave
