building r-devel on RedHat 7.1 with gcc 3.1.1

Has anyone tried to build r-devel on a RedHat 7.1 with the gcc 3.1.1
compiler?  I didn't have problems with gcc 2.95.x or gcc 3.0.4, but when I
ran the configure with gcc 3.1.1 I got the following error:

checking whether gcc accepts -M for generating dependencies... yes
checking whether gcc supports -c -o FILE.lo... yes
checking how to get verbose linking output from g77... -v
checking for Fortran 77 libraries...  -L/home/rpeng/install/atlas
-lreadline -ldl -lncurses -lfrtbegin -lg2c -lm -lgcc_s
checking for dummy main to link with Fortran 77 libraries... none
checking for Fortran 77 name-mangling scheme... lower case, underscore,
extra underscore
checking whether g77 and gcc agree on int and double... configure:
WARNING: g77 and gcc disagree on int and double
configure: error: Maybe change CFLAGS or FFLAGS?

Should I have set some configuration option?  Or is this more likely a
problem with my gcc installation/build?

I'm trying to build r-devel (8/30/02) source.
