Hmm, I think you are confused. Even without __declspec(dllimport),
user code that calls such functions don't need any special
modifications or options. Having the dllimport declaration just makes
the calls a tiny bit faster as they don't go through the stubs from
the import library.

(For variables that are imported from DLLs the situation is different,
they *must* be declared as dllimport to be referenced correctly in
user code.)

The more important reason for decortaing functions with macros like
this is to explicitly specify the calling convention to be used. But
even that is not terribly important. Glib, gtk, etc and apps that use
them get along fine without. (Many other libraries, though, do feel
that they need to specify calling convention in the headers.)
