Subject: Add a -fbuilding-cabal-package flag
X-Git-Url: http://git.megacz.com/?p=ghc-hetmet.git;a=commitdiff_plain;h=7026ce88b5c7753fe5c3d4164c02c9de58bf6979

Add a -fbuilding-cabal-package flag
This means GHC knows whether it's building a Cabal package, or just
Haskell sources. For example, it may wish to give different error
messages when building a Cabal package.
