For an R package?

Here is what the current Rmpi has in src/Makefile.in:

  # -*- Makefile -*-  vim : ft = make


As you can see, it only sets arguments to the compiler, not the compiler

Rmpi is a pretty good package to study as Hao as been diligently working at
it for many years, and has it working for a great number of system and
compiler choices.  

Did that help? If not please rephrase the question.
