 141 /* There are several classifications of routines:
 142
 143      (1) Symbols used only within the library,
 144      (2) Symbols to be exported from the library,
 145      (3) Symbols to be exported from the library, but
 146          also used inside the library.
 147
 148    By telling the compiler about these different classifications we can
 149    tightly control the interface seen by the user, and get better code
 150    from the compiler at the same time.
 151
 152    One of the following should be used immediately after the declaration
 153    of each symbol:
 154
 155      internal_proto     Marks a symbol used only within the library,
 156                         and adds IPREFIX to the assembly-level symbol
 157                         name.  The later is important for maintaining
 158                         the namespace partition for the static library.
 159
 160      export_proto       Marks a symbol to be exported, and adds PREFIX
 161                         to the assembly-level symbol name.
 162
 163      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 164
 165      iexport_proto      Marks a function to be exported, but with the
 166                         understanding that it can be used inside as well.
 167
 168      iexport_data_proto Similarly, marks a data symbol to be exported.
 169                         Unfortunately, some systems can't play the hidden
 170                         symbol renaming trick on data symbols, thanks to
 171                         the horribleness of COPY relocations.
 172
 173    If iexport_proto or iexport_data_proto is used, you must also use
 174    iexport or iexport_data after the *definition* of the symbol.  */
