Nowadays you just pkgadd it from some common Oracle repository. Well, at
least on x86, as I have no idea if SPARC Solaris offers it. But the
comment is explicitly about x86.

So assertion is that compiler recognizes option -sparc? Don't see
anything of the sort in the manual page. Well, I can see that
contemporary compiler would recognize -xarch=sparc, but that's
*contemporary* version. But more importantly manual also says that
-xarch=v9 is equivalent to -m64 -xarch=sparc and -m64 is the essence of
this configuration. So -xarch=v9 is right, because it generates 64-bit
code and works with all compiler versions. [Well, one can probably argue
that it's time to reconsider meaning of "all compiler versions" in the
context, yet it wouldn't make "just say "sparc"" right :-)]
