  83 /* There are several classifications of routines:
  84
  85      (1) Symbols used only within the library,
  86      (2) Symbols to be exported from the library,
  87      (3) Symbols to be exported from the library, but
  88          also used inside the library.
  89
  90    By telling the compiler about these different classifications we can
  91    tightly control the interface seen by the user, and get better code
  92    from the compiler at the same time.
  93
  94    One of the following should be used immediately after the declaration
  95    of each symbol:
  96
  97      internal_proto     Marks a symbol used only within the library,
  98                         and adds IPREFIX to the assembly-level symbol
  99                         name.  The later is important for maintaining
 100                         the namespace partition for the static library.
 101
 102      export_proto       Marks a symbol to be exported, and adds PREFIX
 103                         to the assembly-level symbol name.
 104
 105      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 106
 107      iexport_proto      Marks a function to be exported, but with the
 108                         understanding that it can be used inside as well.
 109
 110      iexport_data_proto Similarly, marks a data symbol to be exported.
 111                         Unfortunately, some systems can't play the hidden
 112                         symbol renaming trick on data symbols, thanks to
 113                         the horribleness of COPY relocations.
 114
 115    If iexport_proto or iexport_data_proto is used, you must also use
 116    iexport or iexport_data after the *definition* of the symbol.  */
