checked sources with static code analysis tool [cppcheck]

[GoogleCodeExporter]

What steps will reproduce the problem?
1. download cppcheck at http://sourceforge.net/projects/cppcheck/
2. cppcheck --enable=all [tinyXML++-soures]
3. receive warnings

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
svn head

Please provide any additional information below.

The tool discoverd a few stylistic issues like an operator= overloading
that returns void! Normally it should return a reference to itself (==*this).

    void operator=( const TiXmlElement& base );

Another possible issue is a not initialized class member in constructors.
It is allways whise to do this, because you set your members to a defined
status during object creation. Otherwise thier value is undefined.

Here is the output from cppcheck:
