I know minpack.lm and nlmeODE used to fail R CMD check in the examples on
the real gcc 3.4.2. I've just tested they on an AMD machine under FC3, and
they seem OK -- what I am not sure is if they ever failed there (they did
on i686).

At a quick glance the embedded reference in etc/Makeconf to gcc 3.3.3 when
compiling packages with Fortran is not causing problems as 3.4.2 has
reorganized where things are.

My tests are on a server in a server room, and at present Xvfb won't run
on it (I think it needs cleaning up after the upgrade), which limits the
testing I can do tonight.

Brian
