Care telling what that 'MPI' is?

They don't exactly "change" to lower case, they are lower case all the
time.  FORTRAN 77, the language compiled by g77, is 100%
case-insensitive --- it's the one where you can write 'r Et   U      r  N'
and get the exact same effect as if you'd typed 'return' or 'RETURN'.  

g77 follows Unix traditions, converting everything to lowercase first
thing in the morning. Function names like MPI_something simply cannot
happen, at object file level, for a Fortran 77 compiler.
