<quote> -Wchar-subscripts Warn if an array subscript has type char. This is a common cause of error, as programmers often forget that this type is signed on some machines. This warning is enabled by -Wall. </quote> I haven't tried it but -Wno-char-subscripts should be the compiler switch. I committed this patch before other people's feedback arrived. Please feel free to revert my changes. > > -Brian >
