Compilation failure with clang 19

[outpaddling]

Bifrost has worked fine for years on numerous FreeBSD versions. Compiling on FreeBSD 15-current produces the following, however:

/usr/ports/wip/bifrost/work/bifrost-1.3.5/src/DataStorage.tcc:81:69: error: no member named 'sz_link' in 'DataStorage<Unitig_data_t>'
   81 |         for (size_t i = 0; i != sz_link; ++i) unitig_cs_link[i] = o.sz_link[i].load();
                                      |                                                                   ~ ^

FYI, hayzamjs proposed a fix for this, and later discovered that it had been proposed before:
