 181      (3) Symbols to be exported from the library, but
 182          also used inside the library.
 183
 184    By telling the compiler about these different classifications we can
 185    tightly control the interface seen by the user, and get better code
 186    from the compiler at the same time.
 187
 188    One of the following should be used immediately after the declaration
 189    of each symbol:
 190
 191      internal_proto     Marks a symbol used only within the library,
 192                         and adds IPREFIX to the assembly-level symbol
 193                         name.  The later is important for maintaining
 194                         the namespace partition for the static library.
 195
 196      export_proto       Marks a symbol to be exported, and adds PREFIX
 197                         to the assembly-level symbol name.
 198
 199      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 200
 201      iexport_proto      Marks a function to be exported, but with the
 202                         understanding that it can be used inside as well.
 203
 204      iexport_data_proto Similarly, marks a data symbol to be exported.
 205                         Unfortunately, some systems can't play the hidden
 206                         symbol renaming trick on data symbols, thanks to
 207                         the horribleness of COPY relocations.
 208
 209    If iexport_proto or iexport_data_proto is used, you must also use
 210    iexport or iexport_data after the *definition* of the symbol.  */
