R-2.2.0 compilation problem

I tried to compile R-2.2.0 just now.  configure worked fine, but
compilation stopped with

ld: Undefined symbols:
restFP
saveFP
/usr/bin/libtool: internal link edit command failed
make[3]: *** [libR.dylib] Error 1
make[2]: *** [R] Error 2
make[1]: *** [R] Error 1
make: *** [R] Error 1
octopus:~/scratch/R-2.2.0%

This has been written up many times already.  It would be nice if it  
was in the documentation.

g77 can only be used with gcc-3.x and earlier.  The default compiler  
on Tiger is gcc-4.

All you need to do to build with g77 on Tiger is use the command
sudo gcc_select 3.3
which will make gcc-3.3 the default compiler and it will all work.
