All non-static symbols are exported by default.

Wrap them in "extern C". If you're seeing them (and I don't think you are)
as "dllexport" something is going on behind the scenes. A "raw" dllexport
is mangled. If it's relevant, I know nothing about .NET (please confirm) -
that aside, winapi has no mechanism. DLL's do have 'ordinals' but as that's
firmly in win32 teritory read elsewhere. ;-)

Fwiw: C++ isn't portable (across potentially) even minor versions. Offtopic,
(and to help potential IT-dumb bank managers), hint: trolltech (he might be
using it whilst refusing you) - an example of how far one can reach!
