/**
@brief Specify when local functions can be passed as template parameters
without introducing any run-time overhead.

If this macro is defined to <c>1</c>, this library will assume that the
compiler allows to pass local classes as template parameters:
@code
    template<typename T> void f(void) {}

    int main(void) {
        struct local_class {};
        f<local_class>();
        return 0;
    }
@endcode
This is the case for C++11 compilers and some C++03 compilers (e.g., MSVC), but
it is not the case in general for most C++03 compilers (including GCC).
This will allow the library to pass local functions as template parameters
without introducing any run-time overhead (specifically without preventing the
compiler from optimizing local function calls by inlining their assembly code).

If this macro is defined to <c>0</c> instead, this library will introduce
a run-time overhead associated to resolving a function pointer call in order to
still allow to pass the local functions as template parameters.

It is recommended to leave this macro undefined.
In this case, the library will automatically define this macro to <c>0</c> if
the Boost.Config macro <c>BOOST_NO_CXX11_LOCAL_CLASS_TEMPLATE_PARAMETERS</c> is
defined for the specific compiler, and to <c>1</c> otherwise.

@See @RefSect{getting_started, Getting Started} section,
@RefSect{advanced_topics, Advanced Topics} section,
@RefMacro{BOOST_LOCAL_FUNCTION_NAME}.
