But if I'm reading the page right, it's valid to do: __declspec(nothrow noreturn) and token pasting will only cover the first word of the space-separated list. I think we're stuck on the wrapper re-write approach. >> The other, equally extreme, solution is to add >> >> #ifdef _MSC_VER >> # include <stdlib.h> >> # include <setjmp.h> >> # include <process.h> >> #endif > > Is this the complete list of MSVC include files that use > __declspec(noreturn)?

I'm leaning towards "#define noreturn /**/" as well. -- Eric Blake ebl...@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
