To continue the compilation, rerun configure using --disable-spinlocks. However, performance will be poor. Please report this to pgsql-bugs(at)postgresql(dot)org(dot)It looks like s_lock.h currently has coverage for amd64 using gcc, or sparc64 using either compiler, but not for amd64 using Sun's cc. Please feel free to send a patch, or you could pester Sun to send us one (Josh?)
SunStudio is supported on the HEAD (8.2). Spin lock problem is know issue in version 8.1.4. I don't know if latest 8.1 branch contains backport.
