build and release 5.34

[shawnlaffan]

We should build and release a version of 5.34, if only for the sake of major version completeness.

This was the original intent of #39 but discussion has become much broader.

The risk is that it won't compile with gcc13, or the patches we are using for 5.36 will not port across. We won't know until we try, though.

Is version 5.34 ready now? What's the progress so far?

[shawnlaffan]

No progress yet. I'm busy the next few weeks so the next chance I'll have is late September.
