GCC 3.1:

temp.cpp:2: warning: keyword `export' not implemented, and will be
ignored

Since it recognises it and warns too,  things are enough good in terms
of ANSI C++ compliance.

Keep in mind that "export" templates are a tough thing to be
implemented, that's why the usage of the keyword export for template
classes and functions, it is something that indicates special condition
in terms of compilation process. I guess things will get better in some
future release.
