bug#58254: 29.0.50; Untracked lib/assert.h with Clang 14

[Basil L. Contovounesios]

Severity: minor
Tags: patch

In a fresh Git worktree:

  $ ./autogen.sh all && ./configure CC=clang && make && git status
  [...]
  On branch wt/clang
  Untracked files:
    (use "git add <file>..." to include in what will be committed)
          lib/assert.h

  nothing added to commit but untracked files present (use "git add" to track)

This file is not generated with the default CC=gcc; there is only a
lib/assert.in.h present.

Is this TRT?
