First off - this question is too hard for my brain...

I suspect it's more the other way round: That is, gcc (any compiler) probably always knew what the last named parameter was, as it is the last one with a symbol name and a type associated with it, so surely must appear in the parsing... So I guess what has happened is that, in an effort to make the compiler more "standards compliant" they have added logic to detect and complain about the case where the parameter passed to va_start() is *not* the last named parameter. The description of va_start() seems to indicate that the second parameter should be the "the name of the last parameter before the variable argument list, i.e., the last parameter of which the calling function knows the type." That's may guess, anyway; it is detecting a "violation" of the definition of va_start(), even though the compiler is perfectly capably of figuring out what you really meant, and could easily "Do the Right Thing" without you giving it that clue anyway - the compiler can surely find the variable part of the passed parameter list, without you pointing at the "last" variable before it, I would have thought. In the short term, you can presumably switch the order of the parameters "const char *fmt, const char *title", and all will be well? -- Ian SELEX Sensors and Airborne Systems Limited Registered Office: Sigma House, Christopher Martin Road, Basildon, Essex SS14 3EL A company registered in England & Wales.
