Thanks for that.  I've tried using 'winemaker --console' and 'configure',
and
running make compiles the source files and then runs winebuild successfully.

But the final step is to produce a .so file (g++ -shared ...), and the only
executable produced is
a soft link to /usr/bin/wine.  Is there any way to get it to produce an
executable?
Using the --cuiexe flag with winemaker give the same result.
