That is a workaround for the bug about the partial specialization of
boost::is_enum<std::pair<T, U> >
being too late.
The bug has been in Boost-1.62 only. For that version (currently the
default version in Debian-testing), we include a header from Boost
container as soon as possible: in `<CGAL/config.h>`.
- move `CGAL_WARNING` in `<CGAL/config.h>`,
- create the macro `CGAL_pragma_warning`,
- use `CGAL_pragma_warning` to simplify `<CGAL/license/lgpl.h>` and
`<CGAL/license/gpl.h.in>`.
- add messages in `include/CGAL/license/generate_files.cmake`
- add test files, that do nothing but can be modified to check errors
and warning.
`BOOST_HAS_VARIADIC_TMPL` and `BOOST_NO_CXX11_VARIADIC_TEMPLATES` can be
wrong, with Boost-1.57 and gcc>=5.0.
Fixes the following warnings with gcc>=5.0 in C++98 mode:
> CGAL-4.8-Ic-106/include/CGAL/array.h:78:31: warning: variadic templates only available with -std=c++11 or -std=gnu++11
> template< typename T, typename... Args >
> ^
> CGAL-4.8-Ic-106/include/CGAL/array.h:80:28: warning: variadic templates only available with -std=c++11 or -std=gnu++11
> cpp11::array< T, 1 + sizeof...(Args) >
> ^
> CGAL-4.8-Ic-106/include/CGAL/array.h:81:42: warning: variadic templates only available with -std=c++11 or -std=gnu++11
> make_array(const T & t, const Args & ... args)
> ^
- Change the way the macros `CGAL_CAN_USE_CXX11_THREAD_LOCAL` and
`CGAL_CAN_USE_CXX11_MUTEX` are defined, so that other compilers are
also supported.
- Add the macro `CGAL_CAN_USE_CXX11_ATOMIC` and the header
`<CGAL/atomic.h>`.
The deprecated names may be removed from future versions of Boost, and
we do not want our C++11 support be dropped for users using newest
versions of Boost.
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
