Comment (by rwbarton):

 Oh yes, I see `clang -E -traditional` doesn't expand the `printTest` macro
 because of the space after the macro name.

 We could fix the test to be clang-compatible of course, but I don't know
 whether that is the right thing to do. Perhaps the fact that ghci has
 invoked clang at all indicates that something has already gone wrong.
