Apparently, Automakes prior to 1.10 do not automatically substitute the absolute path directory variables abs_srcdir abs_top_srcdir abs_builddir abs_top_builddir that Autoconf computes (since ca. 2003) into the Makefiles. This leads to a subtle error when OPM-Core is used in conjunction with dune-common's DUNE_CHECK_MODULES (or, more appropriately, our own OPM_CORE_CHECK_MODULES) macro that gets invoked through dunecontrol. The *_CHECK_MOUDLES macro contains an unconditional statement that uses 'abs_top_srcdir' to compute the absolute path to the current module's top source directory. When abs_top_srcdir is unset, the root becomes unset too, whence the subsequent existence and validity checks fail due to incorrect CPPFLAGS and/or LDFLAGS. It will also fail to locate the 'dune.module' dependency file. By explicitly substituting the above variables into the Makefiles, as was also done in revisions 5819 and 5845 of dune-common's Subversion repository, we're guarding against this particular failure mode. Tested on: CentOS 5.8 (Autoconf 2.59, Automake 1.9.6)
