My recollection is that Sun's own tokenizer doesn't support 64-bit 
constants, and generates code which forces partial 32-bit behaviour 
(like 32-bit truncating values before testing). I recall having to 
create 64-bit values with two separate constants and lxjoin - I'll check 
on Monday to make sure this is still the case.

In other words, I'm not clear providing 64-bit constant support buys you 
much in terms of SPARC64 support.
