+Fix hurd build with hidden support
 
-This need not strictly be a TopGit branch, but it is for easy synchronization
-between different machines.
-
-As the baseline is merged into the topic branches, it is forward-only.
-
-To advance it:
-
-    $ echo [SHA1] > .topdeps
-    $ git commit -m Advance. -- .topdeps
-    $ tg update
-
