Ok, that's what I suspected vis a vis gcc/cc but I didn't know what
platform. Thanks. So what's the reason for SPARC32_Solaris?

Yes, certainly if you're building on Solaris then Solaris Studio (cc) is the
obvious correct choice.

So what about 5 and 6 below? Are they built with gcc or Solaris Studio?

And is there an issue of not having access to SPARC build hardware?
