Operating systems other than Linux that come with a manufacturer supported
MPI library (like IRIX) put the mpi.h/mpif.h files directly into
/usr/include so that they appear as an OS facility, rather than an add-on.
Doing it this way (and putting libraries - or at least some links - into
/usr/lib) makes life easier for the developers as well, because the files
will be picked automatically by the compiler without need of -I or -L (of
course, one can use "mpicc" & co. just as well...)
One can use LAM-MPI to provide the same "look" on a Linux system, so
installing the headers in $PREFIX/include (with PREFIX=/usr in this case)
makes sense.
Also if one chooses PREFIX=/usr/local/lam-7.0 (I personally do it like
this to be able to install several versions of LAM-MPI and MPICH), it
really makes no sense to have include files in
/usr/local/lam-7.0/include/lam.
