 203 # to do such aliasing in C. C++ is different: The compiler generates aliases
 204 # for implementation reasons, and the mangled names used to encode argument
 205 # and return value types are difficult to handle well in mapfiles.
 206 # Furthermore, the Sun compiler and gcc use different and incompatible
 207 # name mangling conventions. Since ON must be buildable by either, we
 208 # would have to maintain two sets of mapfiles for each such object.
 209 # C++ use is rare in ON, so this is not worth pursuing.
