G_GINT4_CONSTANT() *isn't* 2.10-and-later, and we've been using it for  
a while:

	$ egrep '64.*CONST' epan/*.c
	tvbuff.c:    G_GINT64_CONSTANT(0xffffffffffffffffU),
	tvbuff.c:    G_GINT64_CONSTANT(0x7fffffffffffffffU),
	tvbuff.c:    G_GINT64_CONSTANT(0x3fffffffffffffffU),
	tvbuff.c:    G_GINT64_CONSTANT(0x1fffffffffffffffU),
	tvbuff.c:    G_GINT64_CONSTANT(0x0fffffffffffffffU),
	tvbuff.c:    G_GINT64_CONSTANT(0x07ffffffffffffffU),
	tvbuff.c:    G_GINT64_CONSTANT(0x03ffffffffffffffU),
	tvbuff.c:    G_GINT64_CONSTANT(0x01ffffffffffffffU)

Unless 2.10 changes G_GINT64_CONSTANT() *not* to work if you put a U  
at the end of the constant, we can just use G_GINT64_CONSTANT();  
alternatively, we could perhaps do

	#ifndef G_GUINT4_CONSTANT
	#define G_GUINT64_CONSTANT(c)	something that sticks a "U" immediately  
after the constant and passes it to G_GINT64_CONSTANT()
	#endif

in some appropriate header file if there's a way to do that with the C  
preprocessor.
