Hi,
	I am new to c++, and I am having real problems with static members
	in that I cant work out how to get gcc to create the static
	element.  All the books I have seem to treat static members as
	trivial, but maybe they arent.

	This is the error:

	x.o: Undefined symbol __5thing$i referenced from text segment

	It seems fairly obvious that gcc hasnt allocated the data
	object, so what do I have to do to make it work?

	I would expect that the constructor is not necessary this
	example.  It is there because I thought that the compiler
	might not create the variable until it was actually newed.

	Thanks for you patience.
	I dont think I like c++ very much!  Maybe I'm getting too old
	for this business!
Russ
