Hi guys,

This is more clang CPP funniness — I've patched this kind of thing before (e.g. https://ghc.haskell.org/trac/ghc/attachment/ticket/8445/fix-xcode5-cpp-errors.patch). Basically clang CPP can't handle the space before the open-paren, so it needs to be removed to be recognized and processed as a macro.

Cheers
Luke

these were added by me, but these are CPP macros that should be always
defined (in HsVersions.h). Also, the problem is not a general one, as
you can see on https://travis-ci.org/nomeata/ghc-complete/builds)

Do you have any idea what might be unusual about your CPP setup?

Greetings,
Joachim
