In what cases, if any, are parameters that are const (rather than non-const
parameters that point to a const object) useful?
C is pass-by-value, so it's not as if the caller will see

Comparing to other print-function with a 'len' as last parameter,
I think not. Looking through interface.h for *_print() functions, only these
have a 'const u_int' as last arg:
openflow_print, ahcp_print.

The prototype and implementation of 'zmtp1_print_datagram()'
is slightly different; the prototype has a 'const u_int len' as the last
parameter. Whereas the implementation has no 'const'. Hence
I get a warning from MSVC. Hence:
diff -u3 Git-Latest/print-zeromq.c ./print-zeromq.c
