   // Warn if CTAD was used on a type that does not have any user-defined
-  // deduction guides.
-  if (!HasAnyDeductionGuide) {
-    Diag(TSInfo->getTypeLoc().getBeginLoc(),
-         diag::warn_ctad_maybe_unsupported)
-        << TemplateName;
+  // deduction guides, but do not warn if the deduction guide is in a system
+  // header on the assumption that the support is intentional there.
