This specific issue should be fixed with 
<https://cgit.freedesktop.org/libreoffice/core/commit/?id=0f4f5621d194c9221b55bb4a20a251a0bb497d69> 
"Use compat::isLookupContext."

However, most people (esp. those writing plugins) probably use newer 
Clang than 3.6 by now, so there may be more issues with older Clang 
remaining in compilerplugins/clang/ that remained undetected for a while.

We removed plugin support for Clang < 3.4 with 
<https://cgit.freedesktop.org/libreoffice/core/commit/?id=733198de1b7fc3907609217147704f493f6146e6>, 
and I'd like to bump the baseline again in the future, depending on the 
oldest version that people are using (for a good reason).  Any specific 
reason you're using Clang 3.6?
