Cabal --builddir

[Neil Mitchell]

Hi,

Cabal documents itself as having a --builddir command to change the
placement of dist stuff, which is fantastic.

However, running with GHC 6.8.3, Cabal 1.6.0.2, I get:

cabal build --builddir=../../../_make/Tools/ext/haddock-0.9/dist
setup.exe: Unrecognised flags:
 --builddir=../../../_make/Tools/ext/haddock-0.9/dist

i.e. cabal accepts the --builddir command, but the setup that cabal
builds doesn't. Why?

Thanks

Neil
