Not necessarily.  These tools should be backward compatible
(althought they sometime failed to).

Odd.

Any chance we can see this macro?  Actually I'd like to know the
exact sequence of commands which are being run.  From your
description I understand something more or less like this:

if test x"$srcdir" = x'.'; then
  for comp in gcc_2.95.3 ...; do
    for rel in release debug ...; do
      for lib in GL mesa ...; do
        dir=$comp-$rel-$lib
        mkdir -p obj/$dir 
        (cd obj/$dir &&
        ../../configure --with-comp=$comp --with-rel=$rel --with-lib=$lib)
      done
    done
  done
  exit
fi

Also, now I don't really undestand what you meant with the
following:

 >>> If I try to build the software without this extra object
 >>> directory the .deps directories are created.

Is this a build with that macro disabled?

Please, send the output of

  % ./config.status --help

and

  % rm -Rf kernel/framework/.deps
  % sh -x ./config.status kernel/framework/Makefile depfiles
