Machine:	sparc
Version:	gcc version 2.3.1
OS:		SunOS Release 4.1.2
problem:	
1 - The methods in a parameterized class are not implemented by the compiler
    if the definitions are not included in the class definition.  For
    example:

	//////////////////////////////// bar.h
	template<class T>
	class Bar
	{
		T data;
	public:
		inline Bar(T i);
		T get(void);
	};
	
	
	template<class T> inline 
	Bar<T>::Bar(T i)
	{
		data = i;
	}
	//////////////////////////////// EOF
	//////////////////////////////// bar.C
	#include "bar.h"
	
	template<class T> T
	Bar<T>::get(void)
	{
		return data;
	}
	//////////////////////////////// EOF
	//////////////////////////////// user.C
	#include <stdio.h>
	#include "bar.h"
	
	main()
	{
		Bar<int> bi(2);
	
		printf("%d\n", bi.get());
	}
	//////////////////////////////// EOF

    when compiled with: gcc-2.3.1 -o test bar.C user.C generates the
    following linktime error:

	ld: Undefined symbol 
	   _get__t3Bar1Zi
