--- Comment #4 from Christos Zoulas <christos at zoulas dot com> --- I believe that -pedantic enables other "pedantic" warnings which I don't belive I want. I can add a specific printf format that does not accept %m, but I would still need to add a syslog format that does (and annotate the syslog functions with that instead of printf). Perhaps it is possible to have a separate -W switch that will enable this behavior (warn for %m in printf formats), and add a syslog format that allows %m. I think that we want to encourage people to write portable code, and using %m in printf isn't. My goal is to differentiate between syslog-like functions that support %m and printf-like functions that don't. Is adding a separate -W flag to enable warnings for %m in printf and a syslog format acceptable? I think that non-glibc systems will benefit from that.
