It was more than copy/paste problems.

The example in the manual declared a function:

unsigned int subtest(void *);

without using it.

It did:

static char input_str[] = "[.wrk]";
...
input_dsc.dsc$w_length = sizeof(input_str);

which I believe must be off by 1.

It did not declare return type of main and it made all variables
global instead of local in main, which is valid C but not very
good C.
