   but that raises the problem of what type to give the symbol.  If we use

   a prototype, it'll conflict with the definition given in this file and

   others.  If we use __typeof, we discover that not all symbols actually

   have declarations.  If we use no prototype, then we get warnings from

   -Wstrict-prototypes.  Ho hum.  */
