The DNprogs build with a couple of warnings, for example

connection.cc:932:26: warning: narrowing conversion of ‘(((int)crc) &
255)’ from ‘int’ to ‘char’ inside { } is ill-formed in
C++11 [-Wnarrowing]
connection.cc:932:36: warning: narrowing conversion of ‘(((int)crc) >>
8)’ from ‘int’ to ‘char’ inside { } is ill-formed in
C++11 [-Wnarrowing]
connection.cc:932:26: warning: narrowing conversion of ‘(((int)crc) &
255)’ from ‘int’ to ‘char’ inside { } is ill-formed in

connection.cc:932:36: warning: narrowing conversion of ‘(((int)crc) >>
8)’ from ‘int’ to ‘char’ inside { } is ill-formed in

readwrite.cc:98:16: warning: deprecated conversion from string constant
to ‘char*’ [-Wwrite-strings]
readwrite.cc:98:16: warning: deprecated conversion from string constant
to ‘char*’ [-Wwrite-strings]
...

I didn't try to set any language mode with any -std option. Maybe that
fixes at least C++11 warnings.

Anyway, the results seem to work. However I can't build an RPM (binaries
are what I need).
'make rpm' fails with

install: failed to access
‘/root/decnet-dnprogs/dnprogs-2.61-orig/rpmbuild/etc/rc.d/init.d/decnet’: Not
a directory
make[2]: *** [install] Error 1
make[2]: Leaving directory /root/decnet-dnprogs/dnprogs-2.61-orig/scripts'
make[1]: *** [install] Error 2
make[1]: Leaving directory /root/decnet-dnprogs/dnprogs-2.61-orig'
make: *** [rpm] Error 2

That's only the first of several failures. I can work/hack around them
by changing ./dnetd/Makefile, ./Makefile, ./rpm.spec and
finally manuall doing a rpmbuild. But I'm not an rpm expert. So maybe
someone wants to have a look at this.
