most recently in the message quoted above. That's a long time ago, so
I don't remember if you tried it then, but I've never heard a
complaint from anyone else that it doesn't work.

How do you do that? (More explicitly, what steps would I have to take
to redefine things like find.exe and sort.exe in Rtools so that R would
know how to find them and use them? I can't figure that out from the
earlier parts of these messages.)
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.

To most Windows users, the "Rtools install" would seem to refer to
getting the bundled Rtools30.exe from the CRAN web site, double-clicking
on it, selecting the options form the GUI windows that appear, and
clicking "install". There is no option in this procedure to change the
names of find or sort.
As far as I can tell, the steps you are recommending take place in an
earlier build step. This would require the user who wants to do this to
rebuild Rtools in its entirety, which is more trouble than it is likely
to be worth. Especially when you can avoid the problem by using your own
batch script or perl script to reset the path on those relatively rare
occasions when you need to use Rtools. Since buiilding Rtools for a
Windows machine is something than CRAN does on a regular basis, why
can't they just change the names there (and not bother the UNIX users,
and probably not even bother the UNIX users who find themselves banished
to the Windows wilderness). Just call them "unixfind" and "unixsort"
and everyone will be able to figure it out....
