Sorry I should have been more specific.  I tried exactly what you 
suggest, but when I try to compile with the 64-bit C++ compiler (xlC_r 
-q64) I get an error on the first file:

xlC_r -q64 -bmaxdata:0x70000000 -c -DNDEBUG -O -I. -I./Include 
-DHAVE_CONFIG_H  -o Modules/ccpython.o ./Modules/ccpython.cc

"./Include/pyport.h", line 480.2: 1540-0859 (S) #error directive: 
"LONG_BIT definition appears wrong for platform (bad gcc/glibc config?).".
So, it appears that either LONG_BIT is defined incorrectly, SIZEOF_LONG 
is defined incorrectly or LONG_BIT is not supposed to equal 8 * 
SIZEOF_LONG in the 64-bit case.  Do you know which it is?
