Re: Emacs 28 on OSX: emacsclient.c:1415: warning: implicit declaration of function 'openat'

[Keith David Bershatsky]

The gdb backtrace text file colorUsingDefaultColorSpace.txt relates to _only_ 
the change of deviceRGBColorSpace to genericRGBColorSpace.

The gdb backtrace text file unsignedlong.txt relates to _only_ the change the 
change of [self getRed:&r green:&g blue:&b alpha:&a]; to [[self 
colorUsingDefaultColorSpace] getRed:&r green:&g blue:&b alpha:&a];

The gdb backtrace text file both_changes.txt relates to both of the suggested 
changes.

Thanks,

Keith
