So far I never encountered any difficulties with it under linux. I tried different settings, and it looks like the code that is enabled for autogen >= 5.18, but apparently the 5.18 behaves like the old version, so this is probably not a back-port of a new feature. My guess is that simply the version should be checked for autogen >= 5.18.1 ? > * Your comment > > /* > * Before Mac OS X 10.7 <i386/setjmp.h> doesn't mark longjump noreturn. > */ > > is wrong, however: even the 10.7 <i386/setjmp.h> does lack the > annotation, and in 10.8 (as I'd seen in 10.11 and 10.12) the > declaration has moved to <setjmp.h> and is properly annotated.

Do you want an updated patch with these changes? Bernd.
