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