Comment (by judah):

 Christian, I agree that conditional compilation in Haskell libraries is
 undesirable, but the problem here is with header files in the framework
 itself, not with libraries that {{{#import}}} the framework.

 My proposed fix was that if a header file is part of
 {{{GNUreadline.framework}}}, it should *always* (not conditionally) import
 other readline headers as {{{<GNUreadline/*>}}}.  That's necessary given
 how GHC currently behaves; and it will still work once #1798 is
 implemented (although that proposal could make this change unnecessary).

 Given that #1798 won't be done until 6.10 at the earliest, is there any
 problem with making this change for now?
