config.h.in wants to be free^Wrebuilt

[Phil Edwards <phil at jaj dot com>]

Last week I had a brief go at making the v3 configury work with autoconf
2.5x.  (No go, they still have weirdness with cross-compilers.)  I did
however find some things which we'll probably want to change, and I'm
going to check in some comments in configure.in to that effect.

But in testing, I found that config.h.in gets rebuilt even with our
current setup, i.e., just run autoheader and you get a different output
file than what's in CVS.  The diff is below.  I don't know what changed
to cause these results, but it looks like folks might be forgetting to
run autoheader before committing a configury change.

I'll check this in with my 2.5x comments once I do some more tests.
