ghc-6-4-bld2.msi: html version of users_guide missing

[Claus Reinke]

the pdf version is there, but the link to the html version is dangling.

$ ls /c/ghc/ghc-6.4/doc/
ANNOUNCE  LICENSE  VERSION  object-io.ps
Cabal.ps  README   html     users_guide.pdf

$ ls /c/ghc/ghc-6.4/doc/html/
Cabal  hslibs  index.html  libraries  object-io

$ fgrep users_guide /c/ghc/ghc-6.4/doc/html/index.html
          <B><A HREF="users_guide/index.html">The User's Guide</A></B>

cheers,
claus
