Not all of them, but many surely do.
When we knew we were supposed to provide a method, but we didn't implement
it then a FIXME message should appear.

Yep, in this case they would appear exactly the same as a call
to a generic missing function (like it was an ActionScript coding error).

It is not possible to distinguish them, but enabling the verbosity
should be pretty simple, or it might actualy be already activated
by -v (log_error and log_warning are). In any case, setting up
a .gnashrc is not a big deal if your debugging Gnash or a flash

It's a setting of RcFile (libbase/rc.h).
