 166      (1) Symbols used only within the library,
 167      (2) Symbols to be exported from the library,
 168      (3) Symbols to be exported from the library, but
 169          also used inside the library.
 170
 171    By telling the compiler about these different classifications we can
 172    tightly control the interface seen by the user, and get better code
 173    from the compiler at the same time.
 174
 175    One of the following should be used immediately after the declaration
 176    of each symbol:
 177
 178      internal_proto     Marks a symbol used only within the library,
 179                         and adds IPREFIX to the assembly-level symbol
 180                         name.  The later is important for maintaining
 181                         the namespace partition for the static library.
 182
 183      export_proto       Marks a symbol to be exported, and adds PREFIX
 184                         to the assembly-level symbol name.
 185
 186      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 187
 188      iexport_proto      Marks a function to be exported, but with the
 189                         understanding that it can be used inside as well.
 190
 191      iexport_data_proto Similarly, marks a data symbol to be exported.
 192                         Unfortunately, some systems can't play the hidden
 193                         symbol renaming trick on data symbols, thanks to
 194                         the horribleness of COPY relocations.
 195
 196    If iexport_proto or iexport_data_proto is used, you must also use
 197    iexport or iexport_data after the *definition* of the symbol.  */
