The comp.lang.c++ FAQL is available by anonymous ftp at
sun.soe.clarkson.edu in the file pub/C++/FAQ (though there's not much
on templates).

Different compilers currently do not handle the generation of template
functions in the same way.  The ARM leaves a lot unspecified and I'm
not sure what ANSI C++ will say about it.  Make sure you read your
compiler manuals as there are often different ways to do it even with
the same compiler, each method offering different tradeoffs.

The easiest way to do deal with this under BC++ (and I believe gcc) is
to just #include the .cpp file containing the non-inline template
functions in the corresponding header file.

	// List.h
	#ifndef List_H
	#define List_H

	template<class T> class List { /*...*/ };
	//...

	#ifndef DONT_NEED_CPP
	#include "List.cpp"
	#endif

	#endif // List_H
