would it be possible to add some cmake flag that would allow the user to choose whether to respect the libclang.exports file or not ?

@bkramer I can verify that after building this with clang 3.9 in release mode it does not work anymore like expected. everything is fine in debug mode

ok after i checked out a recent version of clang and applied the patch D15729 i can verify, that one does not have to add the symbols to the libclang.exports file.

I am finally back at work and happy to see that some effort already went into the patch that i initially wrote some time ago (D5611)

last patch was against the wrong revision.
