* This file defines the interface to declare and export from the DLL an STL

* vector of some type. To use this file you must #define a number of symbols
|
|
* and then #include it from a .h file. You also must do the same thing with
|
|
* vector_something_src.cxx from a .cxx file. This is necessary because of
|
|
* the complexity involved in exporting a vector class from a DLL. If we are
|
|
* using the Dinkumware STL implementation, it is even more complex. However,
|
|
* all this complexity is only needed to support Windows builds; Unix shared
|
|
* libraries are able to export symbols (including templates) without any
|
|
* special syntax.
