Well, what declaration or type is on syslog.h:68 ?  (Possibly look at 
preprocessed output (-E) in case some macro substitution is going on).

That sounds quite fascinating :)  (Note that with musl you'll probably run 
into problems with stdarg.h usages; musl want's to rely on compiler 
provided builtins for those, which TCC doesn't provide, even though our 
implementation is binary compatible with the psABI, ... one of those days 
...)

... ah, oh, see?  :)  Hmm, so is TCC's stdarg.h really being included, or 
is it picking up some other stdarg.h?
