Hi -- I am trying to build boost on a 64-bit AMD Opteron but make it 
yield
32 bit code. The reason for this is I want smaller executables and 
memory
footprint (Side note: if you do pmap on even a small hello world 
program
on an 64 bit Opteron it requires 10 MB of virtual memory vs. 1.2 MB 
if
compiled in 32 bit mode -- Can you believe it?).
Have you considered just how much larger the virtual address space is 
on a 64 bit machine?  :-)
