[R] R_problem_buf in the S.h files & lists in .C

[Duncan Temple Lang]

I didn't see any mention of this in the material on CRAN.  The two S.h
files define R_problem_buf as a real symbol rather than simply
declaring its existence. As a result, a shared library that links two
or more files that include this will get duplicate symbol complaints.
Since it is not defined elsewhere in the code, someone has to define it.

A secondly thing is the documentation for .C() and company. It omits
what type list() objects have when passed to a C routine. It should
read void *, which is actually a SEXP * in this case. (I know, I
should be using .External but I am trying to keep the code for the
different S's and R's together until I have to abandon things.)
