 171 /* There are several classifications of routines:

 173      (1) Symbols used only within the library,
 174      (2) Symbols to be exported from the library,
 175      (3) Symbols to be exported from the library, but
 176          also used inside the library.
 177
 178    By telling the compiler about these different classifications we can
 179    tightly control the interface seen by the user, and get better code
 180    from the compiler at the same time.
 181
 182    One of the following should be used immediately after the declaration
 183    of each symbol:
 184
 185      internal_proto     Marks a symbol used only within the library,
 186                         and adds IPREFIX to the assembly-level symbol
 187                         name.  The later is important for maintaining
 188                         the namespace partition for the static library.
 189
 190      export_proto       Marks a symbol to be exported, and adds PREFIX
 191                         to the assembly-level symbol name.
 192
 193      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 194
 195      iexport_proto      Marks a function to be exported, but with the
 196                         understanding that it can be used inside as well.
 197
 198      iexport_data_proto Similarly, marks a data symbol to be exported.
 199                         Unfortunately, some systems can't play the hidden
 200                         symbol renaming trick on data symbols, thanks to
 201                         the horribleness of COPY relocations.
 202
 203    If iexport_proto or iexport_data_proto is used, you must also use
 204    iexport or iexport_data after the *definition* of the symbol.  */
