Uninitialized static structure in generator.c/write_sum_head

[John E. Malmberg]

In the module generator.c, there is a static struct sum_struct null_sum 
that is not initialized by any way that I can determine in the routine 
write_sum_head.

Shouldn't it more correctly be:

     const struct sum_struct null_num = {0, 0, 0, 0, 0, NULL};

This would also allow the declaration for the write_sum_head routine to 
be as below, since the data that sum is pointing to is never modified.

     void write_sum_head(int f, const struct sum_struct * sum)
