Resolving multiple definitions of the same template function

When the prelinker generates template functions, it resolves multiple function definitions as follows:

• If a function has both a specialization and a generalization, the specialization takes precedence.
• If there is more than one specialization, the prelinker issues a warning message.

Because the link step does not remove unused instantiations from the executable program, instantiating the same functions in multiple compilation units may generate very large executable programs.
