Checks whether the allocator used by g_malloc() is the system's
malloc implementation. If it returns %TRUE memory allocated with
malloc() can be used interchangeable with memory allocated using g_malloc().
This function is useful for avoiding an extra copy of allocated memory returned
by a non-GLib-based API.
A different allocator can be set using g_mem_set_vtable().
Return: if %TRUE, malloc() and g_malloc() can be mixed.
