Aren't you supposed to "make distclean" whenever you reconfigure?
That's what I do in every project, because I don't trust the Makefiles
to DTRT in such case.  E.g., what about all the *.o files you didn't
remove?

Thanks.

However, I don't like rules that depend of Makefiles, because they
tend to be re-run too much for no good reason.  Note that this will
re-make the docs each time you reconfigure, even if you didn't change
the configuration.

But if I'm the only one who dislikes this, I won't object to the
change.

How can we not distribute them when gdb.texinfo @include's them, and
needs that for setting some of the variables the manual uses?  If we
don't distribute them, end users will be unable to rebuild the manual.
What am I missing here?
