Thanks for the advice on the flags. FYI, I've attached the current flags (using Intel's tools). At least if I modify this file for usage with LAM, the flags work pretty well.

On recognizing Intel's MPI and finding the appropriate flags: I tried a few commands which seem to produce the desired output. Not knowing anything about autoconf syntax I tried my best to add a function (or whatever autoconf calls it) "test_intelmpi()" to dune-common/m4/mpi-config.m4 which actually does the job for me. That is, Intel's MPI library is recognized and dune-common is compiled without any problems. In the likely case that this solution requires further fine-tuning these are the commands I tried:

Hopefully, the first lines of these suffice to identify Intel's MPI lib.

>mpiicc -show
icc -I/opt/intel/impi/3.2.1.009/include -L/opt/intel/impi/3.2.1.009/lib -Xlinker --enable-new-dtags -Xlinker -rpath -Xlinker $libdir -Xlinker -rpath -Xlinker /opt/intel/mpi-rt/3.2.1 -lmpi -lmpiif -lmpigi -lrt -lpthread -ldl

>mpicc -show
gcc -I/opt/intel/impi/3.2.1.009/include -L/opt/intel/impi/3.2.1.009/lib -Xlinker --enable-new-dtags -Xlinker -rpath -Xlinker $libdir -Xlinker -rpath -Xlinker /opt/intel/mpi-rt/3.2.1 -lmpi -lmpigf -lmpigi -lrt -lpthread -ldl

mpiicc -compile-info and mpiicc -link-info produce the exact same output as mpiicc -show
mpicc -compile-info and mpicc -link-info produce the exact same output as mpicc -show
