...bstitute
LAPACK/BLAS at dynamic linking time, unless all LAPACK/BLAS
implementations agreed on such a C interface. Now the substitution is
based on the original Fortran interface.
In case of R, if we only used the included reference BLAS/LAPACK, we
could do this, define our wrappers, say "c_dgemm" for "dgemm", change R
to call via that interface, ask maintainers of all packages to change
their code to call via their interface, and this should work with all
Fortran 2003 compilers.
But, R is often used also with optimized BLAS/LAPACK implementations
that can be substituted...
