 128 /* There are several classifications of routines:
 129
 130      (1) Symbols used only within the library,
 131      (2) Symbols to be exported from the library,
 132      (3) Symbols to be exported from the library, but
 133          also used inside the library.
 134
 135    By telling the compiler about these different classifications we can
 136    tightly control the interface seen by the user, and get better code
 137    from the compiler at the same time.
 138
 139    One of the following should be used immediately after the declaration
 140    of each symbol:
 141
 142      internal_proto     Marks a symbol used only within the library,
 143                         and adds IPREFIX to the assembly-level symbol
 144                         name.  The later is important for maintaining
 145                         the namespace partition for the static library.
 146
 147      export_proto       Marks a symbol to be exported, and adds PREFIX
 148                         to the assembly-level symbol name.
 149
 150      export_proto_np    Marks a symbol to be exported without adding PREFIX.
 151
 152      iexport_proto      Marks a function to be exported, but with the
 153                         understanding that it can be used inside as well.
 154
 155      iexport_data_proto Similarly, marks a data symbol to be exported.
 156                         Unfortunately, some systems can't play the hidden
 157                         symbol renaming trick on data symbols, thanks to
 158                         the horribleness of COPY relocations.
 159
 160    If iexport_proto or iexport_data_proto is used, you must also use
 161    iexport or iexport_data after the *definition* of the symbol.  */
