Cabal bug?

[Niklas Broberg]

Some more wierd behavior:

I have a configure script that uses some custom --with-X flags. I now
want to access this script through Cabal. If I say

> ./configure --with-sessiondb-driver=PostgreSQL

the @DB_UPPER@ markers in my files get exchanged for "PostgreSQL". If
I instead write

> runhaskell Setup.hs configure --with-sesisondb-driver=PostgreSQL

the @DB_UPPER@ markers become "yes". How come?
