In the attached test case, the OPTIONS_GHC pragma is ignored in the
 included header file. However, the problem goes away if you use --make,
 surprisingly. Unfortunately, in my real code, the problem does not go away
 when I use --make.

 I'd argue that this (putting OPTIONS_GHC in a #include file) should work,
 because

 (a) It worked with ghc 6.4.2

 (b) It's useful to centralise options in one place

 (c) Logically, if the first line of the #included file is the OPTIONS_GHC
 pragma, and the #include line is on the first line of the .hs file, the
 OPTIONS_GHC should appear to ghc to be in the right place.

 Compile this test case with: ghc -cpp test.hs
