   By telling the compiler about these different classifications we can
   tightly control the interface seen by the user, and get better code
   from the compiler at the same time.

   One of the following should be used immediately after the declaration
   of each symbol:

     internal_proto	Marks a symbol used only within the library,
			and adds IPREFIX to the assembly-level symbol
			name.  The later is important for maintaining
			the namespace partition for the static library.

     export_proto	Marks a symbol to be exported, and adds PREFIX
			to the assembly-level symbol name.

     export_proto_np	Marks a symbol to be exported without adding PREFIX.

     iexport_proto	Marks a function to be exported, but with the 
			understanding that it can be used inside as well.

     iexport_data_proto	Similarly, marks a data symbol to be exported.
			Unfortunately, some systems can't play the hidden
			symbol renaming trick on data symbols, thanks to
			the horribleness of COPY relocations.

   If iexport_proto or iexport_data_proto is used, you must also use
   iexport or iexport_data after the *definition* of the symbol.  */
