SUMMARY
=======
The sample code below illustrates how to use the [list::merge] STL function(s)
in Visual C++.
Note that there are some differences in the implementation of the Standard C++
Library components in Visual C++ version 4.2 versus later revisions. The
relevant sections of code below compile conditionally based upon the value of
_MSC_VER.
