-In Stroustrups's "The C++ Programming Language" Appendix A: r.14.9
-(ANSI/ISO resolutions) a mechanism is described for the explicit 
-instantiation of template member functions (that are not inline). 
-At this time some compilers do not support this mechanism (and use
-a template database snd/or smart linker instead). Other compilers 
-(such as g++) provide only limited support for other forms of
-instantiation (g++ currently supplies a smart linker for templates
-only on a limited set of OS).
-
-Since there is no standard mechanism for instatiating
-templates at this time we are defining the preprocessor flag 
-EXPL_TEMPL in the build system when the compiler supports
-explicit instantiation and the compiler does not support
-automatic instantiation via a smart linker and/or template
-database.
-
-EPICS codes that use templates may need to include a code block
-as follow that instantiates the template only once into each
-program.
