Cannot convince cabal to do dynamic linking using the config file

Hi. As described in the wiki, I have modified my ~/.cabal/config in the following way:

As advised in the wiki page: https://wiki.archlinux.org/index.php/Ha … th_linking
I have modified my `~/.cabal/config` in the following way

library-vanilla: False
shared: True
executable-dynamic: True

Even though, cabal doesn't seem to pick up those options:

$ cabal install quickcheck  --reinstall
Resolving dependencies...
In order, the following will be installed:
QuickCheck-2.11.3 (reinstall)
Warning: Note that reinstalls are always dangerous. Continuing anyway...

cabal: Error: some packages failed to install:

exception was:
ExitFailure 1

If I explicitly pass the flags to `cabal`, then the installation succeeds:

$ cabal install --enable-shared --enable-executable-dynamic --disable-library-vanilla quickcheck --reinstall
Resolving dependencies...
In order, the following will be installed:
QuickCheck-2.11.3 (reinstall)

Installed QuickCheck-2.11.3

It looks like cabal ignores the configuration of these options. What's more interesting, setting the prefix in `~/.cabal/config` seems to work.
Do you have any idea how to convince cabal to link everything in accordance to how Arch handles things Haskell?
