This macro is always defined. Its value will be true when assertions are defined
and false when assertions are not defined. This macro can then be used in place
of a true false constant, such as is needed for CGAL_NOEXCEPT.
This macro is available for future compatibility with c++11, which
by default marks destructors noexcept(true). Some destructors
in CGAL do throw exceptions an so should be marked noexcept(false).
Since noexcept is not available in c++0x and below the macro is
disabled when CGAL_CXX11 is not defined since it is not required.
This macro has to be larger than the default value
and it must be set before including <boost/parameter.hpp>
Instead of setting it to 12 in the packages that
need it, we do this in <CGAL/config.h> and produce
an error if a user has set it to a value < 12
somehow, boost/random.hpp includes boost/type_traits/has_binary_operator.hpp,
and the "parse error" happens in this file (as said in the bug report)

A warning of clang showed me my mistake:

Trivial bug-fix.
CGAL_assume(EX) is like CGAL_assertion, but is not disabled in release
mode. In debug mode, it is similar to CGAL_assertion(). In release mode, it
uses builtins of the compilateur, like the MSVC __assume or the g++/clang
__builtin_unreachable to give an hint to the compiler that some situation
in the code cannot happen.
In order to fix such a warning from g++-4.8:
warning: typedef ‘boost_static_assert_typedef_241’ locally defined but
not used [-Wunused-local-typedefs]
then:
- create one macro CGAL_UNUSED that is "__attribute__ ((__unused__))"
with g++ or empty otherwise,
- use it after BOOST_STATIC_ASSERT in the definition of
CGAL_static_assertion.
The Intel Compiler, even when it tries to emulate the GNU/C++ compiler,
does not implement the GNU extension "statement expressions". The macro
CGAL_CFG_NO_STATEMENT_EXPRESSIONS must be defined with __INTEL_COMPILER is
defined.
When one is using the non-deprecated form of the macro, the version of
the deprecation has to be used - not the version where the original
macro appeared first.
Those cause trouble, because on MSVC the include paths for tr1
components are different from gcc. Instead of fixing up the include
paths depending on platform, just never use a tr1 component. Nothing
of value is lost compared to the boost equivalents and it removes
another code-path.
