+
+	* config/os/bsd/darwin/ppc-extra.ver: New.
+	* src/Makefile.am (libstdc++-symbol.ver): Move outside conditionals,
+	and make dependent on port symbol files.
+	(libstdc++-symbol.explist): Use the generated .ver file, not
+	the template.
+	* src/compatibility.cc [APPLE] (__eprintf): New.
+	* src/Makefile.in: Regenerate.
+	* configure.host (powerpc*-*-darwin*): Define
+	port_specific_symbol_files.
