Thanks for the comments Mike. I've stripped all references to tadpmu
and all ifdef'd out code for now. I'll put it back in when I deliver a
real tadpmu.
(One exception: the platmod still tries to load tadpmu, but doesn't
bitch on the console if it can't find one.)

The problem with cruft like this is it makes it harder for people to
understand just what's going on. As a general rule, unused code
(including makefile bits) should be kept out of the gate.

The Makefile.*.shared files were introduced to deal with makefile text
that is shared between the open and closed trees.
In the interest of simplicity, platforms that are entirely open-source
should not use the .shared pattern. If there's a reasonable chance
you'll be adding closed code later, I'd leave it as-is. (Teamware
doesn't cope with renaming a file Foo to Foo.shared and then creating a
new Foo. I haven't checked how well Mercurial copes.)

Historically, there have been problems with project teams promising to
fix something in a followup putback and then not doing so (e.g., the
team gets redirected to work on something else). So there is a strong
preference not to introduce #if 0'd code in the first place.
