There seems to be something wrong with the python installation in Cygwin.
To build the docbook stuff we use the Cygwin a2x utility that depends on
the Cywin python.  There's quite a bit of juggling that goes on here to
keep things straight.  I'm not sure what's happening here.

There shouldn't be any warnings, except if you try to build the pdf docs.
You can check the buildbot output (
https://buildbot.wireshark.org/wireshark-master/waterfall) to see what
should be produced in a build.

My version, in which I have a custom WIRESHARK_VERSION_EXTRA of "-GMB"
shows up as you would like it to, so I'm not sure why yours should be
different.  Maybe this has been caused by your change of git and the old
(broken) version.h is lying around in your build directory.  Whenever you
change fundamental things, I've found it best to delete any existing build
directories, create a new one and run the CMake generation step again.
