Not totally wrong ;-) Doing the equivalent of DLLEXPORT on Linux is
something I have built into the build process of my project. Does not
require knowledge of the name mangling. What it does require is platform
specific linker knowledge, and access to tools that can manipulate linkable
objects. Those requirements are usually around for ELF type system (not just
Linux). All that said, it's probably still too cumbersome for general use.

Looking at the handy shared lib guide...

http://www.fortran-2000.com/ArnaudRecipes/sharedlib.html
Using static and shared libraries across platforms

Gives you some idea of other methods. The ones that mention doing a script
file for "ld" are the hard ones to implement.

Anyway, for simplicity, of maintenance and understanding I'd say use a
separete lanbinding shared library.
