Indeed, there are hundreds of warnings around "pg_printf_attribute_m"
added with gcc 7.3.0 on by ubuntu 18.04 laptop, thanks to 3a60c8ff.
Oh? What warnings exactly? I would not expect any new warnings except
on platforms where gcc believes the local printf is non POSIX compliant,
which certainly ought not happen on any non-obsolete Linux.
Hmmm. Strange. The good news, is sthat it does not show anymore. Maybe
this was because I had not done a "configure" before recompiling. Sorry
for the noise.
