Well, it didn't.  Renaming the old cp.exe to get it out of the way
made the build script continue on and die a bit later (when it got to
an old version of find.exe).

Maybe there was a hidden bug that just got revealed with the newer
DLL.  Here's the exact error I see when using the old cp with the new
DLL:

cp -pr  ../../../library/base  ../../../library/tools
../../../library/methods ../../../library/grid  ../../../library/ctest
../../../library/eda  ../../../library/lqs  ../../../library/mle
../../../library/modreg  ../../../library/mva ../../../library/nls
../../../library/splines  ../../../library/stepfun
../../../library/tcltk  ../../../library/ts ../../../library/R.css
rw1090dev/library
cp: will not create hard link `rw1090dev/library/eda/html' to
directory `rw1090dev/library/eda/Meta'
cp: will not create hard link `rw1090dev/library/mva/html' to
directory `rw1090dev/library/mva/data'

(I said it was copying 30 directories, but it's actually only 15.)
