Jon's new build works. 

I have libintl-1.dllbut not libintl.dll, which is perhaps why Petr's build 
didn't work for me.

Here are dumps from my working 12-point and broken 13-point databases. Sadly, 
the latter appears corrupted :(

If I want to rebuild the 13 point one, can I now use the 12 point as a start 
point? I seem to recall that this used to fail.

What is the latest version of makebearoff.exe? I've just installed from 
Øystein's package, and makebearoff now doesn't respond to the -v or -h switch. 
Does it still work?
