 This was originally spotted and [https://mail.haskell.org/pipermail/ghc-
 devs/2015-February/008407.html posted to the ghc-devs mailing list] by
 Joachmin Breitner, but apparently since nobody has submitted a ticket for
 this relatively serious issue, here it is.  I am quoting Joachim:

 {{{
 while the index at
 http://haskell.inf.elte.hu/docs/7.11.20150222.noWin32/html/libraries/index.html
 exists, navigating to
 http://haskell.inf.elte.hu/docs/7.11.20150222.noWin32/html/libraries/Data-
 Char.html
 yields a 404 error.

 Same for
 http://haskell.inf.elte.hu/docs/latest/html/libraries/Data-Char.html
 }}}

 And [https://mail.haskell.org/pipermail/ghc-devs/2015-February/008408.html
 I have replied] the following to his initial email (I am involved in this
 because I am doing daily snapshots of the documentation through my FreeBSD
 GHC builders):

 {{{
 Yes, I can confirm this bug.  For what it is worth, the files are all
 there, the link appears to be broken: it is missing the subdirectory
 with the name of the package.  That is, the proper link should be
 something like that:

 http://haskell.inf.elte.hu/docs/7.9.20141222.noWin32/html/libraries/base-4.8.0.0
 /Data-Char.html

 (Note the missing "base-4.8.0.0".)  I have checked this with GHC
 7.8.3, and everything is right there, while this problem seems to
 appear with GHC 7.10 RC2 and GHC-HEAD (starting from somewhere between
 mid-September and November -- that is what a quick bisecting tells
 me).
