While it's possible that these warnings on 32-bit builds is just a matter of the compiler being wrong, it could also be that it can't determine all arguments are null-terminated. Specifying max string length in format specifiers seem a benign and cheap safeguard.

Thanks @dholmes-ora and @plummercj I don't know why the compiler is complaining but I'd like it to stop.  If this isn't the best way to do so, please suggest another workaround.  I could also open a new bug to investigate whatever the bug in the 32 bit compiler is and push this workaround, if you would like.

@shipilev there's something wrong with one of the github test machines (error for non-payment) that needs to be fixed.  This builds on 32 bit in our mach5 configuration.

And @cl4es thank you for the suggested workaround.
