        OK. But that was a tool chain transition, and needs be treated
 like any other tool chain transition -- even though we can hide the
 debris arising from such a transition by shipping intermediate files.

        Yes, but we don't frown upon autogenerated  .o files. And lex,
 swig, and yacc output files are also not pre-generated, usually.


        What you are saying, in essence, is that we have not been
 treating autoconf transitions with the care we devote to other
 transitions; and as a result people have started shipping
 intermediate files.

        While I recognize these past lapses, I am not sure why we
 should condone and in the future pander to them -- I am hoping that
 autotools are coming of age, and there shall be few major API changes
 in the future. Post etch, perhaps we can evaluate if overhauling our
 autotools  usage in Debian to allow treating autoconf like we do lex
 and yacc -- and building from sources -- is feasible, or not.
