OK, simple fix, open an Msys box, cd mythtv && make.  Magically it
builds rgb2rgb.c but falls over on linking libswscale.  Then re-start
the installer script and it built everything.  Looks like there's some
kind of environment difference.

Thanks, applied.

That would be preferable but unfortunately the script downloads a
pre-built taglib.  The comments are that cmake is needed to build from
source.  I don't believe this as I have just x-compiled 1.6.3 with only
make.
