I had some problems with g++ and templates, because it doesn't support the
"export" keyword neccessary to use templated that were defined in another
compilation unit. Looking at your code the situation seems to be similar
with VC++ (you have the complete implementation of the templates in the
header file).

What about "Use of function and class templates allowed, but only when
completely implemented in the respective header (no use of the "export"
keyword). Sparse (expr?) use recommended however." ?
