Just installed FreeBSD and I can confirm UnrealIRCd does not build on 10.3 with clang (and without gcc). The error itself is slightly different but probably same cause.

Looks like TRE is being built statically. c-ares and pcre2 are being built correctly (dynamically).

The problem is in the TRE library.
There's no newer version available than we ship. They are still at 0.8.0 from 2009.

They do have a repository at github. But after cloning, you need to run a few commands to make the version usable + package as .tar.gz... this isn't working or at least not producing a working ./configure for all systems.

Update TRE to git version because of FreeBSD build problems with clang

I'll release later today/tomorrow which contains this fix.
