Albrecht Gebhardt had the same bug report a few days ago.  I don't quite
understand what is going on.  configure checks (via AC_C_CONST) whether
`const' works fine.  If not, it defines const as empty in Rdefines.h.
This in turn gets included in all of our source files.  So how can it
happen that const is empty in one place and not in another?

What happens in your Rdefines.h?
