I don't think that is quite right. Its only safe to set this define if
you can guarantee there is no calls to your code before g_type_init (or
g_thread_init directly) is called. This is true for gobject (must call
g_type_init first) and gio (100% gtype library). However, one could
imagine some library of e.g. utility functions that have stuff you can
use before g_type_init() is called.

I wouldn't mind this, but on the other hand its not really a large
maintainance burden, is it?
