Please test: release candidates for Cabal/cabal-install patch releases on the 1.18 and 1.20 branches

[Johan Tibell]

Ben,

Is this something that worked in cabal-install 1.18.0.5 and that stopped
working in 1.18.0.6 or is it something that didn't work in 1.18.0.5 but you
expected to be fixed in 1.18.0.6? These 1.18 and 1.20 releases just target
a very few critical bugs. They are not attempts to backport all bugfixes
from master.

In 1.18 the critical fixes are:
12a698b6db8a2ca55367c54611a269048f4cef7b Build C sources with -fPIC when
GHC is using dynamic libraries.
4fbb20f52c842a7c7c173555ff7f0c8b5b67dfa1 Support for network-2.6
6f74da062e6d1bdc6db51acd55d0e2676fa56bf2 SavedConfig Monoid instance: make
list fields work like Flags.
7380144203a233f81ff67052fc3256cf47b9b71f cabal update: use sandbox config
file #1884

As for installing, after downloading the two tarballs to a temp dir this
works for me:

cabal install Cabal-1.18.1.5.tar.gz cabal-install-1.18.0.6.tar.gz
