I should have guessed it. Unfortunately I somehow thought, that
memberwise comparison is added implicitly (like the copy constructor and
assignment operator are)...

I looked up this in the Sun compiler C++ user reference - and will try
it out tomorrow:

"When the compiler implicitly instantiates a template class, it
instantiates the static data members, the constructor, and the
destructor. However, the compiler does not implicitly instantiate any
other member function unless the function is explicitly referenced. To
force the compiler to instantiate all member functions when implicitly
instantiating a class, use the -template=wholeclass compiler option. To
turn this option off, specify -template=no%wholeclass, which is the
default."


Rgds,
