* To enable MPI you have to run configure with --enable-parallel.

by Carsten Gräser and myself which allows computations on subsets of grids.  Since
it is not a core module there should be no reference to it in dune-common, however
as long as Bug 230 is not fixed there is no way around it.

one bug and one warning fixed.  The test wanted the MPI_LDFLAGS set in order to look for a sequential UG.  Thanks to Andre Massing

- just giving a more verbose error message doesn't solve the problem

- The issue has been solved within UG.  The UG build system now aborts
  when --enable-dune is set but not __cplusplus.  I had just forgotten
  to close the issue.  Beg your pardon.

Please try to avoid unrelated indentation and whitespace changes in
patches, as the diffs become more difficult to read.

Now configure works even if no fortran compiler is there.
Just how should be!

disable dune libcheck, because AC_TRY_LINK fails, although everythins is OK. Perhaps a libtool problem
