This seems a gcc installation problem. Which shell tools and compiler
are you using? From the message above, I am supposing you are
using the mingw32 version of egcs (there is no -mno-cygwin flags in the
gcc line). Only clue, if this it true, : you get that kind of
error ("cannot exec 'cpp'") if the environment variable
GCC_EXEC_PREFIX is not set correctly.
Anyway, unzip32.dll is not used before your error. So,...

If 'extend' means 'compiling packages' look to the R Venables and
Ripley on-line complement at http://www.stats.ox.ac.uk/pub/MASS2/Compl.shtml.
Note that full installation means more that just recompiling the dll
and, in particular, needs more tool than the one offered by a
standalone VC++ (perl and groff at least).
About embedding, Brian Ripley added to the devel branch (available
as R-devel from CRAN) some code which make this easier than in the past.
Look for an example to the src/gnuwin32/front-ends/rtest.c file which
shows how R.dll and the interpreter can be initialized and used.
However, remember that R-devel should be considered experimental.
I am also pretty sure that R.dll can be re-built using VC++ but this
will require some work (and Brian additions make this point much less
