Something like this:
if True
Ghc-Options: -O -Wall
if impl(ghc >= 7.8.1)
Ghc-Options: -flate-dmd-anal
(I'm not sure if the "if True" hack is still needed, but at one stage it was.)

Hi,
I have a project here where GHC's option -flate-dmd-anal gets out some extra speed but the flag is not available on 7.6.3. How can I specify in the cabal file that I only want to pass this through when building with 7.8.3 or newer? It'd be a shame to not take advantage of the extra speed on 7.8.3 just because we want to support 7.6.3 too for a bit longer. I was unable to find the info online.
Thanks.
