I didn't know the header-only issue and that such a recent
version of Mac OS X is lacking getcontext(). Thanks. So only
10.4.x is having it?
Which version of gcc on 10.3? And is the __builtin_unwind_init()
problem gcc-generic or Mac OS X specific?
And finally, does this workaround effect?
-# elif defined(HAVE_BUILTIN_UNWIND_INIT)
+# elif 0 && defined(HAVE_BUILTIN_UNWIND_INIT)
