Isn't it enough to have the whole header file guarded with the
GTK_FILE_SYSTEM_ENABLE_UNSUPPORTED ifdef? Why should
_gtk_file_system_create() be even more private?

(In maemo we're exporting that symbol as hildon_gtk_file_system_create()
since we need it in hildon-fm...)

There are other symbols intended for derived widgets to use, protected
methods you could say, but as they're not exported you're confined to
gtk only.

Interestingly enough I just noticed none of the private _gtk_* symbols
have 'visibility("hidden")' attribute. Is libtool really doing to right
thing here, or should the private symbols be hidden properly?
