 The code is simplified version of something from Win32 package
 (https://github.com/haskell/win32/blob/master/System/Win32/SimpleMAPI.hsc#L56):

 {{{#!hs
 #{enum Int ,
  , a       = sizeof(int)
 #if 0
  , b       = sizeof(char)
 #endif
  }
 }}}

 {{{
 $ hsc2hs b.hsc -o b.hs-native
 $ hsc2hs b.hsc -o b.hs-cross --cross-compile
 b.hsc:1  sizeof(int)
 #if 0
   is not an integer
 }}}

 I'm not sure if it's a valid .hsc but having at least the same (valid or
 invalid) result in both modes would be nice.
