Just a heads up so maybe others can save some time. Brought up CodeWarrior for Power Architecture, Version: 10.3.3, Build Id:131024 and attempted to run hello_world example according to the quick start instructions. Foolishly, I checked c++ instead of c as project type and the system never got to main().
The problem is already described in the release notes. The workaround is to replace libc++_E500V2.a with libstdc++_E500V2.a. Here's some search strings that may lead someone to the answer more quickly:
static Metrowerks::console_outputbuf<char> fout(stdout);
#endif /* _EWL_WIDE_CHAR */
The good news is that finding the defect was a good exercise in using the debugger.
