Fails to build with tlsdate-helper.c:377:11: error: invalid use of incomplete typedef ‘SSL’ {aka ‘const struct ssl_st’} and subsequent errors.

[dreirund]

I am trying to build on Artix GNU/Linux (rolling release, so software is pretty much up to date) for x86_64 architecture the latest git checkout as well as release 0.0.13.

It fails to build with tlsdate-helper.c:377:11: error: invalid use of incomplete typedef ‘SSL’ {aka ‘const struct ssl_st’} and subsequent errors:
