You'd need to ask a SPARC maintainer. :-)
Seriously, it does look good to my eyes, thanks, Eric! The only question
I have is this: I assume <code>--with-tune=leon</code> is a configure
option, whereas <code>-mtune=leon</code> is a GCC option? For those not
so familiar with GNU tools or GCC, it might be helpful to make this
explicit in the description.
