Thank you for responding.

I should have added -a on my ulimit command.  Here are its results; 
which I believe are not the limiting factor.

%/ > ulimit -a
core file size        (blocks, -c) 1048575
data seg size         (kbytes, -d) unlimited
file size             (blocks, -f) unlimited
max memory size       (kbytes, -m) 32768
open files                    (-n) 2000
pipe size          (512 bytes, -p) 64
stack size            (kbytes, -s) hard
cpu time             (seconds, -t) unlimited
max user processes            (-u) 128
virtual memory        (kbytes, -v) unlimited

Here are my gcc-v results.  They are very similiar.

%/ > gcc -v
Using built-in specs.
Target: powerpc-ibm-aix5.3.0.0
Configured with: ../gcc-4.1.2/configure
    --prefix=/opt/sas/msd/home/barnharj/usr/local
    --program-suffix=-4.1.2
    --enable-threads=aix
    --enable-languages=c,c++,fortran
    --disable-nls
    --with-mpfr=/opt/sas/msd/home/barnharj/usr/local
    --with-gmp=/opt/sas/msd/home/barnharj/usr/local
Thread model: aix
gcc version 4.1.2

My results for gcc -print-multi-lib are indentical to yours.

It should be noted that I did not attempt a 64 bit build.  My system 
is not configured properly for that just yet.

Via private correspondence someone also suggested the following 
system("ulimit -d unlimited") during an R session.  That failed as did 
issuing the command before launching R.

I'll keep investigating.

My call to configure is listed below.

/configure --prefix=$HOME/usr/local --program-suffix=rc --with-readline=no 
 --with-x=no --enable-memory-profiling
