The -R option is actually the default, but it doesn't do a real
recursive diff, all this option does is let cvs itself recurse the
subdirectories and do a diff in each of them. The file names in the
resulting patch has the path stripped from them, so you can't apply this
patch directly using "patch".

I might write a perl mangler to fix this, if it annoys me too much.

About CVS servers not supporting the -u switch, this is for older 'cvs'
that didn't have diff and friends built-in and used the system ones.
Only GNU diff has -u, so CVS servers on commercial Unixes only have -c.
Poor them. :-)
