+ * 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.
