Dear Maintainer,
While working on the “reproducible builds” effort [1], we have noticed
that the nad2bin binary has unreproducible output, as it includes
uninitialized memory state when CTABLE.id's length is less than the
available 80 bytes.
See the attached patch for a proposed solution.
Regards,
Alexis Bienvenüe.

Description: Makes nad2bin output reproducible
Init CTABLE.id char[80] variable with zeroes, so that nad2bin output does
not depend on memory state before call, and hence be reproducible.
