--- Comment #3 from Stas Sergeev <stsp at users dot sourceforge.net> --- Yes, this warning: warning: unknown conversion type character 'P' in format [-Wformat=] can be suppressed with -Wno-format, but it seems to suppress the entire format checking. I only need to suppress "unknown conversion type character" and not all the rest. -Wno-format-invalid-specifier in clang does exactly this, so why not to stay compatible?
