--- Comment #2 from Hannes Hauswedell <h2+bugs at fsfe dot org> ---
What do you mean with "It doesn't work this way"?

Maybe I wasn't clear in my original post; I am not interested in a dispatching
mechanism for the application, I just want to have an mini-application that
returns 0, 1, 2, 3 or 4 depending on which feature level is available on the
current computer.

How is my example different from
https://gcc.gnu.org/onlinedocs/gcc/Function-Multiversioning.html (other than
using the new feature levels)?

Thanks
