Ok, stop, stop!! Much easier if I just enable those flags myself and work through them! ---

Well thanks! I was getting tired of all that work 😃 I was going for “obsessively persuasive :D” anyway, if you then need to lower the warning level again, I will keep an eye on possible warnings that slip in from time to time and report them here ---

Hi, I have noticed the great improvement! There are still some lingering, though, which make me suspect that you didn’t enable the warnings for: “Implicit Signedness Conversions” (-Wsign-conversion, CLANG\_WARN\_IMPLICIT\_SIGN\_CONVERSION), “Implicit Conversion to 32 Bit Type” (-Wshorten-64-to-32, GCC\_WARN\_64\_TO\_32\_BIT\_CONVERSION) “Suspicious Implicit Conversions” (-Wconversion, CLANG\_WARN\_SUSPICIOUS\_IMPLICIT\_CONVERSION) “Unused Parameters” (-Wunused-parameter, GCC\_WARN\_UNUSED\_PARAMETER) will you take care of these as well? ---

Yeah, I couldn’t spend any more time on it. I generally do this kind of minor tidying-up when I’ve got a hangover and can’t concentrate on anything more challenging! ---

How many beers does it take? I may afford that after all 😃 ---

`#ifdef __clang__ #pragma clang diagnostic push #pragma clang diagnostic ignored "-Wshorten-64-to-32" #endif ` and ```auto #ifdef __clang__ #pragma clang diagnostic pop #endif ``` should be added around the inclusions of AU source files in juce\_AU\_wrapper.mm (roughly between line 40 and 80) in order to avoid some warnings there. ---

For consistency with the other wrappers, I’d put the “push” section after the inclusion of juce\_IncludeSystemHeaders.h, just to keep the area where they are inhibited to a minimum, and there are no warnings coming from that inclusion that need to be inhibited here.
