Thanks.  Following your suggestion, I was able to build
gcc-4.0.0 RC2 on powerpc-ibm-aix5.2.0.0.

My original limits were

% limit
cputime         unlimited
filesize        1048575 kbytes
datasize        131072 kbytes
stacksize       32768 kbytes
coredumpsize    1048575 kbytes
memoryuse       32768 kbytes
%

I then did 

% unlimit datasize
% unlimit stacksize

(not sure both are necessary) and my new limits were

% limit
cputime         unlimited
filesize        1048575 kbytes
datasize        unlimited
stacksize       4194304 kbytes
coredumpsize    1048575 kbytes
memoryuse       32768 kbytes
% 

With these limits, I was able to build gcc-4.0.0 RC2 on
powerpc-ibm-aix5.2.0.0.  

I still do not know what AIX 5.1 and AIX 5.2 PTFs 
David Edelsohn was referring to ... or where they
are referenced.  But evidently increasing the
data limit was sufficient.
