Yes, such a macro would be useful. To be used at the discretion of the package maintainer (e.g. through a Gnulib module, similar to the 'largefile' module). But do you have an overview which targets are meant in the doc? "old-style stack checking is also the fallback method for ‘specific’ if no target support has been added in the compiler." "Most targets do not fully support stack clash protection." Bruno
