[R-SIG-Mac] R4.0.0 and Makevars

[Roy Mendelssohn - NOAA Federal]

That's muchly.  That was my memory.  I just wanted to reconfirm.  I do have the emails about OpenMP.  Right now I don't need that,  but I might down the line.  I was just glad that I have been able to get the upgrade to go smoothly.  A fellow on R-bloggers posted a really nice script to upgrade.  What us nice is it re-installed not only packages from CRAN but from GIthub also.

I thought I had saved that email but i can't find it,  and I just looked at the archives and can't find it either.  If anyone has that info I would appreciate it.  I know you remove all the clang references that might have been there,  I have kept the gfortran to gfortran8.2,  is there anything else.
