It is worse than that. `R`'s configure script identifies clearly how to
mix C and fortran, i.e. it looks at your fortran compiler and identifies
the necessary mangling. At least one of the standard `R` packages that are
built by default just assume `gfortran` style mangling for their calls to
blas/lapack functions. So whatever fortran compiler you use to build `R`
you have to make it behave like `gfortran`.
