1 patch for repository http://darcs.haskell.org/cabal: Wed Aug 25 16:11:06 EEST 2010 Dmitry Astapov * Auto-reconfiguration when .cabal is newer than setup-config This patch adds "ConfigFlags" to the "LocalBuildInfo" and reuses them to perform "configureAction" when .cabal file is changed. This has the same effect as re-running "configure" with the most recent used set of options, which should be the sensible thing to do. Closes #294, #477, #309 and #518. This is my first Cabal patch and first post to cabal-devel, so please review carefully ;)
