- Mac: revise XCode project to use OS 10.4 SDK for building PowerPC libraries
and executables so that we can use weak-linking for APIs not available
before OS 10.4, such as uselocale().
- MGR: Modify SET_LOCALE constructor and destructor to change locale only on
those systems without support for setting locale on a per-thread basis,
such as OS 10.3.9.
NOTE: At this point it appears that Ubuntu and Fedora both support uselocale().
If any platform does not support it, change the "#if 0" gui_rpc_client.h
to "#if defined(some_OS)".
