+      \item Unwind protection is enabled by default (Iñaki in \ghpr{1225}).
+      It can be disabled by defining \code{RCPP_NO_UNWIND_PROTECT} before
+      including \code{Rcpp.h}. \code{RCPP_USE_UNWIND_PROTECT} is not checked
+      anymore and has no effect. The associated plugin \code{unwindProtect}
