 152 /* There are several classifications of routines:

 154      (1) Symbols used only within the library,
 155      (2) Symbols to be exported from the library,
 156      (3) Symbols to be exported from the library, but
 157          also used inside the library.
 158
 159    By telling the compiler about these different classifications we can
 160    tightly control the interface seen by the user, and get better code
 161    from the compiler at the same time.
 162
 163    One of the following should be used immediately after the declaration
 164    of each symbol:
 165
 166      internal_proto     Marks a symbol used only within the library,
 167                         and adds IPREFIX to the assembly-level symbol
 168                         name.  The later is important for maintaining
 169                         the namespace partition for the static library.
 170
 171      export_proto       Marks a symbol to be exported, and adds PREFIX
 172                         to the assembly-level symbol name.
 173
 174      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 175
 176      iexport_proto      Marks a function to be exported, but with the
 177                         understanding that it can be used inside as well.
 178
 179      iexport_data_proto Similarly, marks a data symbol to be exported.
 180                         Unfortunately, some systems can't play the hidden
 181                         symbol renaming trick on data symbols, thanks to
 182                         the horribleness of COPY relocations.
 183
 184    If iexport_proto or iexport_data_proto is used, you must also use
 185    iexport or iexport_data after the *definition* of the symbol.  */
