I don't have recent enough autotools to attempt the change the Makefile.am, but instead restored the removed item from libmpi_usempif08_la_LIBADD directly in Makefile.in. However, rather than fixing the problem, that resulted in multiple definitions of a bunch of _eq and _ne functions (e.g. mpi_f08_types_ompi_request_op_ne_). So, I am uncertain how to proceed. Use svn blame points at a "bulk" CMR of many fortran related changes, including one related to the eq/ne operators. So, I am turning over this investigation to Jeff and/or Ralph to figure out what actually is required to fix this without loss of whatever benefits were in that CMR. I am still available to test the proposed fixes. Happy hunting... Somebody owes me a virtual beer (or nihonshu) ;-) -Paul -- Paul H.
