 143 /* There are several classifications of routines:

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