The stuff after the colon in a constructor declaration provides
information
on intializing either base or member variables.  However in this case
it specifies exactly what would have happened anyhow (derived default
construtor invokes base default constructor), so it's unclear why it was
written this way.  COnsider:

	derived::derived() : base('d') {  ...

This would ininitialize the base class with the char literal 'd'.

Note that specifying these initializers only provides the arguments
to initialize the listed base classes or members.  It DOES NOT change
the order of construction.
