Thanks for the review.

But, my intention was to just fix the `ERR_get_error_line` deprecated
warning (as mentioned in the commit header) and not all the OpenSSL
deprecated warnings found in `sigstruct.c`

Do I need to fix all these OpenSSL deprecated warnings in `sigstruct.c`
in order to get this patch merged?

Thanks,
Dhanuka
