UNW_INIT_SIGNAL_FRAME is not a #define anymore

It looks like UNW_INIT_SIGNAL_FRAME is now an enum and no longer a #define:

As a result, the following check and usage are not working correctly:

Well, that's unfortunate. I suppose we could use a bit of SFINAE (substitution failure is not an error) magic for the .hpp part. Not fun.

Any ideas?
