Ah, I'd thought you'd just misread the documentation, but looking closer
I realize that you're probably not understanding the significance of this
warning.  I think what's wrong is you have not #include'd "fmgr.h" which
is where PG_MODULE_MAGIC is defined.  It's not exactly clear to me why
that's resulting in a warning rather than an error, but certainly this
is indicating a problem.
