Is this in reference to _GLIBCXX_USE_ICONV? That is only useful for the codecvt specializations that use iconv. As of 4.0.0, this is in libstdc++-v3/include/ext/codecvt_specializations.h. Or is this in reference to runtime testing? That looks different. However, what you are suggesting is still easy to do. -benjamin -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22339
