maoing inconsistent 2.13.6 mingw, and fonts

[Graham Percival]

There seems to be a 40% chance of building mingw with lilypad.
Jan and I spent hours looking into this yesterday without being
able to track down the problem.  I ended up building the windows
package twice (I mean, after all the investigations) to get
lilypad in there.  I checked it on my own windows system.

This version includes the first pass at the easier-to-replace font
thingie, which might or might not work for everybody.  Give it a
spin, and we'll shovel this out the door.
