Minor documentation nit, which might apply to the 1.5 branch as well
(didn't check).
README says:

However, following that instruction w/ Sun Studio 12 Update 2 yields:
> cc: Warning: -xarch=v8plus is deprecated, use -m32 -xarch=sparc instead
for every single compilation.
I vaguely recall noting this once before, perhaps 2 years or so.
Additionally, it appears that the "Sun" example is for the 32-bit ABI
and the "GCC" example for the 64-bit ABI.
This is potentially a bit confusing.
