  23    All the #ifdefs in the definitions are quite irritating but
  24    necessary if we want to avoid duplicating the information.  There
  25    are three different modes:
  26
  27    - PROCINFO_DECL is defined.  This means we are only interested in
  28      declarations.
  29
  30    - PROCINFO_DECL is not defined:
  31
  32      + if SHARED is defined the file is included in an array
  33        initializer.  The .element = { ... } syntax is needed.
  34
  35      + if SHARED is not defined a normal array initialization is
  36        needed.
