Which glext.h are you using ? The one from the official registry reads :

#ifndef GL_ARB_vertex_buffer_object
#define GL_ARB_vertex_buffer_object 1
/* GL types for handling large vertex buffer objects */
/* Only used by this extension for now; later needs to be moved earlier 
in glext.h */
#include <stddef.h>
typedef ptrdiff_t GLintptrARB;
typedef ptrdiff_t GLsizeiptrARB;
...
#endif

Which explains the piece of code in ngl.h.
