The camlp4 manual states that the loc variable is bound in the "action"
part of a "level-rules" (i.e. the right hand side of an -> arrow in a
grammar production).
Therefore I guess you should pass loc as a parameter if you invoke
functions from those RHSs which are not defined inside a RHS.
Cheers.
