The 8.3 version of CodeWarrior for Windows does not support locales 
from dynamic libs.  The UseDLLPrefix.h header is commonly used to 
properly set up the import/export flags.  This header will also #define 
_MSL_NO_LOCALE which disables locale support.

When linked against static versions of MSL_All, full locale support is 
available.
