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