  | commit gcc-16-3747-gafa74d37e81
  | Author: Martin Uecker <uecker@tugraz.at>
  | Date:   Tue Jul 29 01:05:00 2025 +0200

  |     c: Warn when returning nested functions that require a non-local context.
  |     
  |     This patch adds a mechanism to keep track whether nested functions require
  |     non-local context because they reference a variable of an enclosing
  |     scope.  This is used for extending the existing -Wreturn-address warning
  | ... 28 lines of the commit log omitted.
