It's there, somewhere, but is apparently not working:

$ grep top_builddir configure |grep pwd
ac_abs_top_builddir=`cd "$ac_dir" && cd $ac_top_builddir && pwd`
top_builddir=`pwd`
ac_abs_top_builddir=`cd "$ac_dir" && cd $ac_top_builddir && pwd`

I think it's not changed, and it's safest just to put MPQC stuff
everywhere. You see, the "higher" directories like

	src/graphics
	src/target3

might include some files from the "lower" one

	src/common

and if the MPQC settings are not set in the "higher" directories as well,
it will not work (that's what just happened).

Ok, done.

Now everything seems to work for me here, except that I still need to
set the top_builddir variable manually (due to obsolete autoconf).

Well, it then just looks that my autoconf is not new enough, right?
I add the other stuff to CVS but keep the current configure script.
