I'm seeing some warnings coming up in GCC 13.2 (default Ubuntu). We're running 11.4 in CI, which isn't much order (2 months) in terms of release dates. @pmienk do we have an upper bound on GCC support presently?
But the compiler flags are opaque to me, I have to assume each library must be compiled with the flags, and otherwise those optimizations will just not be present in the libs without the flags.
