 130 /* There are several classifications of routines:
 131
 132      (1) Symbols used only within the library,
 133      (2) Symbols to be exported from the library,
 134      (3) Symbols to be exported from the library, but
 135          also used inside the library.
 136
 137    By telling the compiler about these different classifications we can
 138    tightly control the interface seen by the user, and get better code
 139    from the compiler at the same time.
 140
 141    One of the following should be used immediately after the declaration
 142    of each symbol:
 143
 144      internal_proto     Marks a symbol used only within the library,
 145                         and adds IPREFIX to the assembly-level symbol
 146                         name.  The later is important for maintaining
 147                         the namespace partition for the static library.
 148
 149      export_proto       Marks a symbol to be exported, and adds PREFIX
 150                         to the assembly-level symbol name.
 151
 152      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 153
 154      iexport_proto      Marks a function to be exported, but with the
 155                         understanding that it can be used inside as well.
 156
 157      iexport_data_proto Similarly, marks a data symbol to be exported.
 158                         Unfortunately, some systems can't play the hidden
 159                         symbol renaming trick on data symbols, thanks to
 160                         the horribleness of COPY relocations.
 161
 162    If iexport_proto or iexport_data_proto is used, you must also use
 163    iexport or iexport_data after the *definition* of the symbol.  */
