      22  
      23     If anything should be added here check whether the size of each string
      24     is still ok with the given array size.
      25  
      26     All the #ifdefs in the definitions are quite irritating but
      27     necessary if we want to avoid duplicating the information.  There
      28     are three different modes:
      29  
      30     - PROCINFO_DECL is defined.  This means we are only interested in
      31       declarations.
      32  
      33     - PROCINFO_DECL is not defined:
      34  
      35       + if SHARED is defined the file is included in an array
      36         initializer.  The .element = { ... } syntax is needed.
      37  
      38       + if SHARED is not defined a normal array initialization is
      39         needed.
