Both are products of the Omegahat project, not of R.  As that project's 
mailing lists appear to be down, I suggest you contact DTL directly.
The versions on CRAN/src/contrib/Omegahat are way out of date.

There are Windows binaries for R 2.0.0 on www.omegahat.org.  I suspect you
have the wrong versions, but it is not clear which you are using,
including whether you are building from source or installing a binary.  
For SWinTypeLibs there are two binary versions there, 0.2-1 and 0.4-0, and
I was unable to find sources for the former.

I have succeeded in building RDCOMClient_0.8-1 from the sources on R
2.0.0, and it does appear to work.  (I did have to make some changes, at
least to the Makefiles.)  My build is available from
