164	bad error message when using configuration flags that were not defined	duncan	byorgey@gmail.com	"Using a flag in an if condition when that flag has not been previously defined gives an unhelpful error message:

{{{
-- flag foo never declared:

if flag(foo)
  blah:
else
  other:
}}}

We get the error message:

{{{
cabal-setup: Environment not defined for all free vars
}}}

The error is reported by {{{Distribution.Configuration.simplifyCondTree}}} but the error should probably be checked for much earlier."	defect	closed	normal	Cabal-1.4	Cabal library	1.2.0	minor	fixed			easy (<4 hours)	6.4.2
