[R] Building and loading a DLL on Windows NT

[Benjamin.STABLER@odot.state.or.us]

It was the case sensitive issue.  I changed the file from .C to .c and I got
the gcc compiler instead of the g++ compiler, which resulted in the function
name staying the same.  Thanks for your help.  Also, I can't seem to find
the Borland tdump utility (everything I can find on the Internet says it
comes with Borland C++ Builder). 

All the best,
Ben Stabler
