Rename them to whatever you want in the Rtools install, then edit the 
definitions.  I think currently they are in src/gnuwin32/Makefile and 
src/gnuwin32/MkRules (one in each), but I'd suggest you just search 
files named M* for the strings "sort" and "find", in case I've got it 
wrong, or it has changed since the last time I looked.

If you try to build R itself rather than just packages, you may need to 
do more edits, because some of the makefiles for things like the jpeg 
libraries weren't written by us, and may have these commands hard-coded.
