Yeah, serinus is visibly still running one of the broken revisions:

configure: using compiler=gcc (Debian 20210527-1) 12.0.0 20210527 (experimental) [master revision
262e75d22c3:7bb6b9b2f47:9d3a953ec4d2695e9a6bfa5f22655e2aea47a973]

It'd sure be nice if seawasp stopped spamming the buildfarm failure log,
too.  That seems to be a different issue:
