[R] configure problems with fortran underscore

[Jim Robison-Cox]

Just after R-0.63.0 came out I reported a problem to the list.  I was
unable to get ./configure to complete it's job, because it couldn't find a
working fortran.  It stopped after trying to test for underscore in
subroutine names.  This was especially perplexing, since I could still
configure the older version (I had 62.2) with no error messages.
I tried suggestions of B.D. Ripley and others to set
the fortran compiler in config.site, but those did not work.  I had
exactly the same problem with R-0.63.1.  Today I discovered that 

./configure --with-f77  does work.  I wonder why it didn't work to set it
in config.site.  When is config.site used?
