The G_CONST_RETURN define in GLib is, and has always been, a bit fuzzy. We always used it to conform to the platform, at least for public-facing API. At first I assumed it has something to do with brain-damaged compilers or with weird platforms where const was not really supported; sadly, it's something much, much worse: it's a define that can be toggled at compile-time to remove const from the signature of public API. This is a truly terrifying feature that I assume was added in the past century, and whose inception clearly had something to do with massive doses of absynthe and opium — because any other explanation would make the existence of such a feature even worse than assuming drugs had anything to do with it. Anyway, and pleasing the gods, this dubious feature is being removed/deprecated in GLib; see bug: https://bugzilla.gnome.org/show_bug.cgi?id=644611 Before deprecation, though, we should just remove its usage from the whole API. We should especially remove its usage from Cally's internals, since there it never made sense in the first place.
