[R-SIG-Mac] Tools Update for R3.5?

Humm…  without the F77 and FLIBS lines I get lots of complaints about:

	… error: unsupported directive '.stabs’

that some from using the old version of gfortran that still exists in /usr/local/bin
With them the gfortran runs nicely, but the first occurrence  of a C routine produces
the error detailed below.  Obviously, there is something fishy with my setup, but 
I thought that fresh R and the two tools packages should have all fitted together.
Thanks again for your suggestions.
