Several files from src/timezone and from src/backend/regex make use of unnamed parameters in function declarations. It wouldn't be difficult to fix everything and call it a day, but I wonder if there are any special considerations here. I don't think that Henry Spencer's regex code is considered vendored code these days (if it ever was), so that seems clear cut. I'm less sure about the timezone code. Note that regcomp.c has a relatively large number of function declarations that need to be fixed (regexec.c has some too), since the regex code was written in a style that makes unnamed parameters in declarations the standard -- we're talking about changing every static function declaration. The timezone code is just inconsistent about its use of unnamed parameters, kind of like reorderbuffer.h. I don't see any reason to treat this quasi-vendored code as special, but I don't really know anything about your workflow with the timezone files. -- Peter Geoghegan
