Workaround for missing 'export' keyword

[Sarir Khamsi]

I have some header files w/ templates that are getting large and want
to break them up (into .hpp & .cpp files). It appears that the
'export' keyword is my friend who will help me to do this. It also
appears that VC++ 5.0 does not support that keyword yet. Does anyone
know of a workaround (besides getting rid of templates)? Thanks.

Explicit instantiation is the answer. A tool that would automatically
manage the list of needed template instantiations would be handy, but
I don't know any such tool. g++/egcs -frepo does something quite
close to that; you might use the .rpo files it produces in order to
build template-instantiation source files, but it would not be exactly
straightforward...
