How to find out if Gnome has been initialised

[Lyndon Drake <lyndon stat auckland ac nz>]

Hi,

At a particular point in my code, I need to find out if Gnome has been initialised
or not (if it hasn't been initialised, I will queue up error messages; otherwise
the message gets displayed immediately).  I could just keep track of whether I
have called gnome_init yet, but I would prefer to use a library function if
possible.

Thanks,
Lyndon
