Just in case, there are Solaris/SPARC systems in the compile farm now:
gcc210 running Solaris 10 and gcc211 running Solaris 11.

I've done some digging on that front:
* While libstdc++-dg-prune does prune notes, it is only used from
dg-test and friends.
* However, the libstdc++ testsuite support code is compiled with
v3_target_compile, ultimately calling DejaGnu's target.exp
(default_target_compile). That does some pruning itself using
prune_warnings, but that mostly applies to linker warnings.
* The libstdc++ testsuite support code is compiled with -w to suppress
warnings, but there's no equivalent way to suppress notes:
diagnostic_inhibit_notes is only called from toplev.c
(process_options) for -fcompare-debug. Maybe that's something to be
