   More precisely, replace 'char' with whatever type guarantees the
   character width you need. Note however that sizeof(symbol) should divide
   HEAD, defined in snowball_runtime.h as 2*sizeof(int), without remainder,
   otherwise there is an alignment problem. In the unlikely event of a problem
   here, consult Martin Porter.
