This may be a bit old hat, but STL Templates are available for Storm C.
H&P says:
"Raymond Zarling did a port of the Standard Template Library (STL) for StormC 4. The STL is a extensive set of algorithms and data structures which enables C++ programmer to more quickly implement their programs. It is also a part of the most recent C++ standard.
The Amiga sources can be found on Aminet; the original sources are at stlport.org and the documentation at sgi.com"To read more about this project, check out
