<DIV dir=ltr align=left><SPAN class=176450116-09112007> mpicc is a
simple shell script which sets the compiler/linker flags/directories (and
more...) etc for you. We recommend that you use the mpicc script to compile
MPI programs. However you could incorporate the necessary changes into your
makefile too.</SPAN></DIV>
