Comment (by anonymous):

 I see the same warning with clang-3.6.1.

 The GCC syntax:
 {{{
 __attribute__((unused))
 }}}
 is accepted by clang,
 [http://llvm.org/releases/3.4/tools/clang/docs/LanguageExtensions.html

 #non-standard-c-11-attributes at least since clang-3.4]. I suggest to
 adapt the following lines, of boost/static_assert.hpp so that clang>=3.4
 is also taken into account:
 {{{
 #!cpp
 #if defined(__GNUC__) && ((__GNUC__ > 4) || ((__GNUC__ == 4) &&
 (__GNUC_MINOR__ >= 7)))
 #  define BOOST_STATIC_ASSERT_UNUSED_ATTRIBUTE __attribute__((unused))
 #else
 #  define BOOST_STATIC_ASSERT_UNUSED_ATTRIBUTE
 #endif
 }}}

 Should I open a new ticket?
