 The "standard" to which you refer is for *USERLAND* code only.  When you
 compile kernel code for Solaris, you are not supposed to use this header
 since it might introduce other (conflicting) symbols.  The Solaris DDI
 specifies the use of <sys/varargs.h> for builing devices drivers and other
 kernel code.
 
 It would be very nice if gcc knew that on Solaris <sys/varargs.h> is
 basically the same as <stdarg.h> and fixincludes automagically took care
 of this.  Which is why I filed the request.
 
 I don't consider the item "closed" in the sense that it is resolved.
 It may be that the gcc team isn't interested in assisting Solaris kernel
 developers -- but the answer "use the standard" is wrong -- the "standard"
 simply doesn't apply here (i.e. to the Solaris kernel).
