extern "C" in gtkthemes.h

[Andreas Simon <asimon ps uni-sb de>]

Hi,

in gtk/gtkthemes.h are 5 function prototypes.

	gtk_themes_init

and
	gtk_themes_exit

are both in the scope of extern "C". But why
not the other three functions

	gtk_theme_engine_get
	gtk_theme_engine_ref
	gtk_theme_engine_unref.

Is this just an error or is there some reason
behind I can't see?

Best regards,
Andreas Simon
