Thanks very much, Brian, especially for answering on a Saturday.

I wasn't sure what "r-patched" meant, and the developer page won't load
for me (using the link from the main R page), so I just altered the code
as suggested (patch shown below for verification) and it is now compiling
happily away, having jumped over this dataentry.c roadblock smoothly.

This makes me happy because I told some students the other day that they
should try Fedora Core 2, and that they should use R on it.

Dan.  (below shows the change I made, in accordance with your suggestion)
