[mythtv] Win Build 23088 Fails

Win Build on 23088 appears to fail due to a missing gettimeofday, required
by upnpdevice.h

In file included from upnp.h:36,
                 from upnp.cpp:24:
upnpdevice.h: In member function `int DeviceLocation::ExpiresInSecs()':
upnpdevice.h:258: error: `gettimeofday' was not declared in this scope
upnpdevice.h:258: warning: unused variable 'gettimeofday'

This I assume is due to the lack of this function in MinGW time.h as
described
http://www.halcode.com/archives/2008/08/26/retrieving-system-time-gettimeofday/

So, after adding the advised code from that link to MinGW include/sys/time.h
and adding #include "sys/time.h" to upnpdevice.h , seems I also have to do
this for taskqueue.h

Then...when we get to httprequest.cpp

At this point I have to admit defeat... this may not be linked to the time.h
issue I guess... I don't know... but I'm guessing whoever is running with
the upnp code isn't testing on win... ;)


Of course, it all compiles fine on my Fedora systems ;) but this seems a lot
of faff for Windows - is there a better way to deal with the lack of this
function in MinGW?

Jonathan
