it mostly compiles, with two caveats:
* c_locale.h needs to include <cstdlib> for declarations of strtod and
friends.
* Solaris <locale.h> only declares the int_p_cs_precedes etc. members of
struct lconv for C99+, but not for C++11+, as it should. I'll file a
bug for that, but for now one can work around the issue by defining
_LCONV_C99 before including <locale> in monetary_members.cc.
With those changes, I can at least build libstdc++ with
--enable-clocale=ieee_1003.1-2008. Bootstrap still running, though.
