[Rd] R.exp file for building packages

I am trying to port some C code from S-Plus (7.0.6) to R (2.4.0) under Windows XP SP2. I use Visual C++ 6.0 to build my library for S-Plus, so I'd like to stick with that set up, if possible. According to the README.packages file, I need the file R.exp (containing functions exported from R.dll, I'm guessing) to build an R package with VC++.

>From what I've read in the archives of this list, R.exp should be installed
in $RHOME/src/gnuwin32 if I chose an appropriate option back when I installed R from the binary. I did a full install of R, but R.exp is nowhere to be found.

Is this file no longer included in the pre-compiled install for Windows? Is there some other way I can recreate the R.exp file? I am currently trying to hack something using

dumpbin /exports "C:\program files\R\R-2.4.0\bin\R.dll" > exports

and editing "exports" into an R.exp file...but I'm not too clear on what the file's supposed to look like.
