  28
  29    - PROCINFO_DECL is defined.  This means we are only interested in
  30      declarations.
  31
  32    - PROCINFO_DECL is not defined:

  34      + if SHARED is defined the file is included in an array
  35        initializer.  The .element = { ... } syntax is needed.
  36
  37      + if SHARED is not defined a normal array initialization is
  38        needed.
