/* See function `init_path' in `kpathsea/tex-file.c' for an example of use.
   The idea is to say PVAR1C(type1, parameter1, ap) in the function header,
   and then end the function with two }}'s.  We do this to avoid having to
   specify the argument list (with types) twice -- once in the function
   header, and once in a (hypothetical) VA_START1.  */
