Subject: Re: [BUG] ioctl: overflow in implicit constant conversion

I have been picking up some old pending issues related to the SANE project.
One of our CI builds is on Alpine and it is generating warnings for 
ioctl() calls from the musl library:

|error: overflow in conversion from 'long unsigned int' to 'int' changes 
value from '2147577985' to '-2147389311' [-Werror=overflow]
||ioctl (fd, PPRSTATUS, &status);

||I see that Olaf Meeuwissen raised this issue a couple of years ago and 
the discussion petered out somewhat and I don't believe that the issue 
was ever really resolved:

Is there any possibility that this could be addressed in the near future?
I see that Alpine have closed their issue and are not interested in 
patching their downstream musl:
