I don't pretend to be a Solaris expert, but the above suggests that you
can upgrade software on that system.

- What's stopping users from installing Sun C 5.9?
- Which systems are we talking about, and do we have any reason to
  believe that they are in wide use in 2024?  Presumably, these machines
  were installed before 2007, when Sun C 5.9 was released.
- Finally, why can't we ask these users to run GCC?  We also don't
  support MSVC, for example, so adding another unportable compiler to
  the list doesn't sound like a disaster (especially since they can just
  upgrade to the next version).

Not sure what this is in reference to.
