If you just want to get rid of the warning, you can edit the settings for the wrapper compilers in share/openmpi/mpif90-wrapper-data.txt, etc. gcc -dumpspecs | grep pthread shows that -pthread adds the preprocessor flag -D_REENTRANT and the linker flag -lpthread. I.e., removing -pthread from the compiler_flags=... line and adding -D_REENTRANT to the preprocessor_flags=... line and -lpthread to the libs=... line should do the job and should be completely equivalent. As far as Intel compilers are concerned -pthread can be replaced with "-reentrancy threaded", but that does not work when the underlying compiler is changed, e.g., OMPI_FC=gfortran.
