D'oh.  I'll tell you when I'm done bashing my head against the table
plate.

Anyway, an easy fix for the reported problem would be the following
patch:

--- tex.el      16 Feb 2006 19:47:47 +0100      5.562

          (setq TeX-master TeX-transient-master))
         ;; Special value 't means it is own master (a free file).
-        ((equal TeX-master my-name)
+        ((and (stringp TeX-master)
+              (string= (TeX-strip-extension (expand-file-name TeX-master))
+                       (TeX-strip-extension (expand-file-name my-name))))
          (setq TeX-master t))
 
         ;; For files shared between many documents.

The normalization of strings for comparison destroys some information
which might be relevant, but maybe it is better than messing around
with `TeX-command-buffer'.  I'll have to look deeper into what
functions would have to be changed if we use the latter, but as far as
I can already see it would be at least `TeX-active-buffer' besides
`TeX-next-error'.
