Funny enough, your code wasn't compiling with gcc 4.4 in _debug_ mode -- linker
error, and I have discovered that this is due to the need of definitions for
these statics:
http://stackoverflow.com/questions/4891067/weird-undefined-symbols-of-static-...,
so I have added them.

Also interesting that gcc in release mode and clang were not requiring this.

   // restrict the number of map transitions to avoid an explosion in
   // the number of maps for objects used as dictionaries.
   inline int MaxFastProperties();
 
   // Maximal number of elements (numbered 0 .. kMaxElementCount - 1).
   // Also maximal value of JSArray's length property.
   static const uint32_t kMaxElementCount = 0xffffffffu;
 
   // Constants for heuristics controlling conversion of fast elements
