Thanks for attaching the config.log. The config.log suggests that this
program:
int
main ()
{
return _Unwind_GetIPInfo ();
}
both compiles and links when using GCC 4.0.1 on Darwin. That would be a
surprising result, as it does not link when using the FSF GCC 4.0.1:
_Unwind_GetIPInfo is undefined. Apparently with GCC 4.0.1 on Darwin
_Unwind_GetIPInfo is defined somewhere.
Can you verify that? If that is correct, then the configure script needs to
check not only that _Unwind_GetIPInfo is available at link time, but also that
it is declared in unwind.h.
