Existing style for these checks doesn't have a space
between the "!" and the "GLIB_CHECK_VERSION".

We could reduce the number of ifdefs we have to have here by
having inside this #if...
void register_glib_mem_trace_functions(void)
(with the GMemVTable and the call to g_mem_set_vtable in it),
and then having an
#else
void register_glib_mem_trace_functions(void)
{
/* Newer versions of glib don't support intercepting the
* memory allocation functions.
*/
}
#endif
Then you can make the callsite un-ifdefed.
