Severity: minor

Hello,

Using the rebuild infrastructure, your package fails to build with clang 
(instead of gcc).

We detected this kinf of error:
http://clang.debian.net/status.php?version=3.4.2&key=WRONG_DEFAULT_DECLARATION

Full build log is available here:
http://clang.debian.net/logs/2014-06-16/texmacs_1.0.7.18-1_unstable_clang.log

Thanks,
Alexander
