Well, the library needs to provide a C symbol named
"plugin_is_GPL_compatible", which the first one does. So I'm not
entirely sure why Emacs is rejecting the library.

If I had to guess, I'd suppose that whatever compiler your using is
noticing that the symbol is never used and removes it. That's an
educated guess based on what I've seen compilers do for other things
that end up being unused; I have no idea if I'm anywhere close to
correct.

On that thought, though, perhaps you could modify the
`emacs_module_init` function to touch the variable (by doing something
like, say, 'plugin_is_GPL_compatible = 42') and see what happens?

HTH,
