Ok, I found another one, though I'm not quite sure what the problem is 
$ perl -e "print pack 'Q',1"
Invalid type 'Q' in pack at -e line 1.

In perl\win32\config.h I have 
/* HAS_QUAD:
 *    This symbol, if defined, tells that there's a 64-bit integer typ
+e,
 *    Quad_t, and its unsigned counterpart, Uquad_t. QUADKIND will be 
+one
 *    of QUAD_IS_INT, QUAD_IS_LONG, QUAD_IS_LONG_LONG, or QUAD_IS_INT6
+4_T.
 */
#define HAS_QUAD    /**/
#ifdef HAS_QUAD
#   define Quad_t long long    /**/
#   define Uquad_t unsigned long long    /**/
#   define QUADKIND 3    /**/
#   define QUAD_IS_INT    1
#   define QUAD_IS_LONG    2
#   define QUAD_IS_LONG_LONG    3
#   define QUAD_IS_INT64_T    4
#endif

And it seems to have made it into Config 
$ perl "-V:.*?quad.*?"
d_quad='define';
quadkind='3';
quadtype='long long';
uquadtype='unsigned long long';

So q/Q for pack/unpack should work, right?
