Comment:

 The problem here is that while UltraSPARC supports CAS even in 32 bit mode
 (the so-called V8+ instruction set), GCC doesn't define
 {{{__sparcv8plus}}} or {{{__sparcv9}}} in 32 bit mode, even when V9 or V8+
 is selected as a CPU. It only sets {{{__sparcv9}}} in 64 bit builds,
 presumably for compatibility reasons. So there is no way to detect whether
 {{{sp_counted_base_gcc_sparc.hpp}}} will work.
