I backed up a bit before delving that far into the code.  Enabling the
win32 stuff in settings.pro seems to have eliminated the
audiotime_updated problem, so it seems that I should have done that
from the beginning.  (Doh!)  I finally have libavcodec, libavformat,
and libmyth compiled.  Plugging away at libmythtv now, wish me luck!

Thanks again everyone!
