But I cannot determine what patch I need to fix it. gnulib-tool installs a bunch of stuff in "lib/" that seems like it ought to handle it, but I get this message anyway:
> No rule to make target '_Noreturn.h', needed by 'distdir-am' I fixed it in one project by adding EXTRA_DIST += lib/_Noreturn.h to the top level Makefile.am, but that seems like the wrong answer. The "stdnoreturn" module should not be exposing its internal workings this way.
