Yes, you can, to my best knowledge, but beware that you will not get for now
the perfect alignment anyway (see my previous message): honestly I don't 
know
the details of Sparc, hopefully what you get now is already sufficient 
to avoid
crashes (not the optimal performance, tough)

This is also an option: however, be warned that on 64-bit machines you 
have to
set _S_align = 16.
