Thanks for doing that. However, it means that 'git am' didn't like this
patch, so I hope I tested it correctly. At any rate, after applying
your patch, removing the generated files, then running 'make dist', and
comparing that to a 'make dist' pre-patch, the minor differences were
all expected (in the Makefiles, not in the generated files).

More than strictly necessary, but I suppose it doesn't hurt, since all
the generated files will have similar timestamps anyways. Certainly
more compact :)

Yep, that's the right approach for something that gets generated into
$(srcdir) for use in the distribution, but which does not need to be
rebuilt by normal users.

Let's make bootstrap.conf mention that rpcgen is now a bootstrap
prerequisite.

I guess I'll see what happens when I try this on Cygwin, but if there
are any followups needed, it should be separate patches. As is, cygwin
already can't use -Werror because of repetitive declarations in the
tirpc headers that trigger one of our default set of gcc warnings.

Nice touch, to help us remember that it is generated.
