Or the G_GINT64_MODIFIER macro.  I seem to remember that there was an 
issue a while ago where the native *printf on Windows used %I64[doxu] 
but the Windows GLib *printf routines used %ll[doxu], or something such 
as that (because it had its own formatting routine).  As such, I checked 
in a change to check for G_GINT64_MODIFIER in the top-level configure 
script (as is done in the Wiretap configure script), and to use that 
when printing gint64/guint64 values, rather than casting to "long long" 
or "unsigned long long".
