 160      (3) Symbols to be exported from the library, but
 161          also used inside the library.
 162
 163    By telling the compiler about these different classifications we can
 164    tightly control the interface seen by the user, and get better code
 165    from the compiler at the same time.
 166
 167    One of the following should be used immediately after the declaration
 168    of each symbol:
 169
 170      internal_proto     Marks a symbol used only within the library,
 171                         and adds IPREFIX to the assembly-level symbol
 172                         name.  The later is important for maintaining
 173                         the namespace partition for the static library.
 174
 175      export_proto       Marks a symbol to be exported, and adds PREFIX
 176                         to the assembly-level symbol name.
 177
 178      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 179
 180      iexport_proto      Marks a function to be exported, but with the
 181                         understanding that it can be used inside as well.
 182
 183      iexport_data_proto Similarly, marks a data symbol to be exported.
 184                         Unfortunately, some systems can't play the hidden
 185                         symbol renaming trick on data symbols, thanks to
 186                         the horribleness of COPY relocations.
 187
 188    If iexport_proto or iexport_data_proto is used, you must also use
 189    iexport or iexport_data after the *definition* of the symbol.  */
