--- Comment #73 from Bernd Edlinger <bernd.edlinger at hotmail dot de> --- Okay, the requirement is only to be able to boot-strap with a released gcc version, so gcc-8 should not use the pragma, while gcc-9 should use the pagma. I was able to bootstrap from x86_64 -> arm cross -> arm native that worked fine. I will guard the pragma with a gcc-version check.
