Yes there is. In fact it's impossible that WoW could use either glWeight or
glWeightPointer, I didn't really look because I just thought that's how it
works. It does not.
WoW uses glVertexAttribPointerARB to set the weight vertex array! Now as far as
I can tell according to the aliasing rules, this is wrong, implementations MAY
alias generic and conventional attributes, but this is not required and the spec
states that setting generic attributes will leave the corresponding conventional
attribute undefined. In fact, aliasing is _forbidden_ if a driver also
implements ARB_vertex_shader. Mesa in fact does not alias, but it seems to work
because it assigns the same AttribPtr to the undefined conventional arrays as to
the corresponding generic arrays (in _tnl_constant_attrib).
