Fred,

The extension is not in the headers yet (who knows why, given that it's been missing for a few dot releases now), but you can still use it if you stick the following in some header file of yours:

// ARB_vertex_buffer_object
#ifndef GL_ARB_vertex_buffer_object
extern "C" {
#include <stdint.h>

typedef intptr_t GLintptrARB;
typedef uintptr_t GLsizeiptrARB;

extern void glBindBufferARB(GLenum target, GLuint buffer);
extern void glDeleteBuffersARB(GLsizei n, const GLuint *buffers);
extern void glGenBuffersARB(GLsizei n, GLuint *buffers);
extern GLboolean glIsBufferARB(GLuint buffer);

extern void glBufferDataARB(GLenum target, GLsizeiptrARB size,
   const GLvoid *data, GLenum usage);
extern void glBufferSubDataARB(GLenum target, GLintptrARB offset,
   GLsizeiptrARB size, const GLvoid *data);
extern void glGetBufferSubDataARB(GLenum target, GLintptrARB offset,
   GLsizeiptrARB size, GLvoid *data);

extern void *glMapBufferARB(GLenum target, GLenum access);
extern GLboolean glUnmapBufferARB(GLenum target);

extern void glGetBufferParameterivARB(GLenum target,
   GLenum pname, GLint *params);
extern void glGetBufferPointervARB(GLenum target,
   GLenum pname, GLvoid **params);
