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

[Balamuta, James Joseph]

Roy,

For R 4.0.0, there is no need to keep Makevars or Renviron's PATH configuration as everything should just "work." The R 4.0.0 binary will look at the default installation location for OS-specific gfortran8.2 or gfortran6.3 version.

Having said this, there is also the OpenMP opt-in possibility for developers (avoid users) detailed here:

Best,

JJB

    Hi All:

    Awhile back Simon posted what if anything should be in your Makevars for R4.0.0 if you needed to compile packages from source.  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.

    Thanks,

    -Roy
