I checked AMD64 Windows7 SP1 VS9.0 2.7. Before the commit, the build 129 failed badly when building ssl:

http://buildbot.python.org/all/builders/AMD64%20Windows7%20SP1%20VS9.0%202.7/builds/129/steps/compile/logs/stdio

IOError: [Errno 2] No such file or directory: 'crypto\\buildinf_amd64.h'

In the first build with the commit, the compilation of ssl succeeded!

http://buildbot.python.org/all/builders/AMD64%20Windows7%20SP1%20VS9.0%202.7/builds/130

"_ssl - 0 error(s), 375 warning(s)"

... but the compilation step still failed, for other reasons. I see that 2 projects failed:

..\..\Modules\expat\xmlparse.c(13) : fatal error C1083: Cannot open include file: 'sys/time.h': No such file or directory
_elementtree - 1 error(s), 9 warning(s)

and

..\..\Modules\expat\xmlparse.c(13) : fatal error C1083: Cannot open include file: 'sys/time.h': No such file or directory
pyexpat - 1 error(s), 1 warning(s)

It may be related to the recent update of libexpat from 2.1.1 to 2.2.0?
