New description:
Typos in flags can lead to confusing problems, especially with large
projects that take a long time to build. A simple check could be quite
useful:
{{{
~> hconfigure -fNonExistentFlag -fSomeFlag
cabal: undeclared flag 'NonExistentFlag'. Declared flags are:
ExistentFlag, SomeFlag
}}}
