#2847: Failure on OPTION_* pramgas other than GHC
-----------------------------+----------------------------------------------

Version: 6.10.1 | Severity: normal

GHC should not attempt to look at other peoples pragmas. For example:
{{{
{-# OPTIONS_DERIVE --derive=Data,Typeable,Eq,Ord #-}
module Example where
data Foo = Bar
}}}
This worked fine with GHC 6.8, but doesn't with GHC 6.10. It says:
{{{
C:\Neil\derive>ghc Example.hs -c
Example.hs:1:11-48:
unknown flag in {-# OPTIONS #-} pragma: _DERIVE
Example.hs:1:11-48:
unknown flag in {-# OPTIONS #-} pragma: --derive=Data,Typeable,Eq,Ord
}}}
I consider this to be a major regression, as it breaks (amongst other
things) the Yhc compiler, the Derive tool, and my thesis. I suspect it
will also break anything Malcolm has set up with OPTION_YHC or OPTION_NHC
pragmas.
