2005-11-17 Geoffrey Keating <geoffk@apple.com>
* 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.
