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