Because, counter to my general rule of thumb of never committing
generated code, I've decided to check in some generated code.  These
files also need to be shipped in the source tarballs.  Long story
short: The templates used to generate the files is *very* particular
about what version of autogen is used and I find I get far too many
users checking out the code who have problems when they use the wrong
version.

I was under the impression that the outputs of targets are always
deleted when 'make clean' is run... at least that's how it seems to
work.
