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