By and large we don't try to support nonstandard compilers on Linux.
Use gcc.

We support icc on Linux, at least to some degree (buildfarm members
mongoose and dugong, for example). I don't see anything wrong with
supporting Sun Studio on Linux, if someone wants to contribute support
for it. Having a buildfarm machine for it would be nice, of course...

Well, that's because (a) someone provided the initial port, and (b)
someone (else?) provided ongoing buildfarm support to see that it
didn't get broken.

If the OP wants to do that work, fine, but don't expect that a complaint
on pgsql-bugs will motivate people who don't have access to the compiler
in question to do anything about it.
