Will give it a shot, thanks, that’s great!

I’m interested in putting in the time to make this build/the tests succeed for
anyone else who wants to use R with the Intel Parallel Studio/oneAPI for sure.
I’m not actually sure whether it makes much difference, vs. gcc, beyond using
the MKL for BLAS/LAPACK, but we do pay for this compiler, and try to use it
anytime we might get a slight boost out of it. One of the reasons too is that
it can do auto-vectorization and build fat binaries for the various processor
instruction sets. I don’t know how much that matters in R either, but if we can
get the best performance out of our system-wide install from that, we want to
do it.

IANAm4P, but that does seem like a pretty good question. I guess there’s
probably some mode of m4 I could run against that and see if there’s any
indication?
