Haddock vs GHC version

I'm running under Windows command prompt under XP, so MSYS issues are
irrelevant:

$ echo %PATH%
C:\Program Files\MiKTeX 2.7\miktex\bin;C:\WINNT\system32;C:\WINNT;C:\WINNT\Syste
m32\Wbem;c:\Program Files\IBM\WebSphere MQ\bin;c:\Program Files\IBM\WebSphere MQ
\Tools\c\Samples\Bin;C:\Program Files\Windows Imaging\;C:\Program Files\Graphviz
2.22\bin;C:\ghc\ghc-6.10.2\bin;C:\ghc\ghc-6.8.3\bin;C:\Program Files\Gtk2Hs\bin;
C:\bin;C:\Program Files\Haskell\bin;C:\Program Files\Microsoft
Office\OFFICE11;C:\ghc\ghc-6.10.2

I've got a haddock in C:\Program Files\Haskell\bin and another in
C:\ghc\ghc-6.10.2\bin (and probably 6.8.3 as well). Is Cabal searching
the path in the right order?

Thanks
