Cannot execute ar.exe on Vista

[gracjanpolak@…]

Cabal cannot execute ar.exe on Windows Vista. Shouldn't check exec bit, just exec, as Vista doesn't have this bit set.

Seems related to problems of GHC when executing as.exe

Following example with HList, happens exactly in the same way on any library cabal project.

This is a bug in the base libs which I believe has been fixed in ghc-6.8. I don't think we intend to workaround the old code just so that new cabal can work with old ghc on Vista.

If this is still a problem with the newer base lib that comes with recent ghc then please reopen.
