Yes, see src/c++98/Makefile.am

# XXX TODO move locale_init.cc and localename.cc to src/c++11
locale_init.lo: locale_init.cc
    $(LTCXXCOMPILE) -std=gnu++11 -fchar8_t -c $<
locale_init.o: locale_init.cc
    $(LTCXXCOMPILE) -std=gnu++11 -fchar8_t -c $<
localename.lo: localename.cc
    $(LTCXXCOMPILE) -std=gnu++11 -fchar8_t -c $<
localename.o: localename.cc
    $(LTCXXCOMPILE) -std=gnu++11 -fchar8_t -c $<


I didn't do that years ago because it would have lost the file history
with subversion. With Git, it should be OK because Git will track the
history across the move. I'll add it to my TODO list.
