 146 /* There are several classifications of routines:

 148      (1) Symbols used only within the library,
 149      (2) Symbols to be exported from the library,
 150      (3) Symbols to be exported from the library, but
 151          also used inside the library.
 152
 153    By telling the compiler about these different classifications we can
 154    tightly control the interface seen by the user, and get better code
 155    from the compiler at the same time.
 156
 157    One of the following should be used immediately after the declaration
 158    of each symbol:
 159
 160      internal_proto     Marks a symbol used only within the library,
 161                         and adds IPREFIX to the assembly-level symbol
 162                         name.  The later is important for maintaining
 163                         the namespace partition for the static library.
 164
 165      export_proto       Marks a symbol to be exported, and adds PREFIX
 166                         to the assembly-level symbol name.
 167
 168      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 169
 170      iexport_proto      Marks a function to be exported, but with the
 171                         understanding that it can be used inside as well.
 172
 173      iexport_data_proto Similarly, marks a data symbol to be exported.
 174                         Unfortunately, some systems can't play the hidden
 175                         symbol renaming trick on data symbols, thanks to
 176                         the horribleness of COPY relocations.
 177
 178    If iexport_proto or iexport_data_proto is used, you must also use
 179    iexport or iexport_data after the *definition* of the symbol.  */
