[xml] Patch to guard #define WIN32_LEAN_AND_MEAN

[Joel Hockey <joelhockey chromium org>]

I'm having errors in chromium doing a rollup to the latest code.

https://logs.chromium.org/v/?s=chromium%2Fbb%2Ftryserver.chromium.win%2Fwin7_chromium_rel_ng%2F39058%2F%2B%2Frecipes%2Fsteps%2Fcompile__with_patch_%2F0%2Fstdout

The error I get is because we already have WIN32_LEAN_AND_MEAN defined.  The attached patch guards the definition.

 #if defined(_WIN32) && !defined(__CYGWIN__)

+#ifndef WIN32_LEAN_AND_MEAN

 #define WIN32_LEAN_AND_MEAN

+#endif

 #include <windows.h>

 #endif

An alternative is:

 #if defined(_WIN32) && !defined(__CYGWIN__) && !defined(WIN32_LEAN_AND_MEAN)

 #define WIN32_LEAN_AND_MEAN

 #include <windows.h>

 #endif

Or feel free to use any other solution.
