I am replying to Professor Ripley's response to my earlier message, which
mistakenly listed the subject. Professor Ripley's response follows.

Nothing: see above. Sorry for the mistake, it was 2:35 in the morning
here...

Thanks. I made the change.

I took out the Defn.h line, and I compiled a file called DOIT.c in the VC++
IDE, along with a DOIT.def file, which contained the following

   LIBRARY DOIT

   EXPORTS
   foo

I linked in the IDE, by including the path to Rdll.lib.
At the moment, even after omitting the Defn.h, I get the same "memory not
read" error. I installed the mingw32 compiler yesterday. I will see if I
can understand how to use that, with gcc and dllwrap, as recommended in 'S
Programming'. Thanks.
