Thanks for the clarification. I thought it was odd to have to cast to a
const in this case. I changed the call like such:

  res = PQexecPrepared(serverp->connection,
        nparm,(const char *const*)parms,NULL,NULL,1);

If the prototype had been for const char** I would not have needed to
change anything, the API author I guess is being thorough.
