+// On gcc (and maybe other compilers?) long long is alway supported
+// but it's use may generate either warnings (with -ansi), or errors

+// BOOST_[APPEND_]EXPLICIT_TEMPLATE_[NON_]TYPE macros --------------------------//
+//
+// Some compilers have problems with function templates whose
+// template parameters don't appear in the function parameter
+// list (basically they just link one instantiation of the
+// template in the final executable). These macros provide a
+// uniform way to cope with the problem with no effects on the
+// calling syntax.
+
+// Example:
+//
+// #include <iostream>
+// #include <ostream>
+// #include <typeinfo>
+//
+// template <int n>
+// void f() { std::cout << n << ' '; }
+//
+// template <typename T>
+// void g() { std::cout << typeid(T).name() << ' '; }
+//
+// int main() {
+// f<1>();
+// f<2>();
+//
+// g<int>();
+// g<double>();
+// }
+//
+// With VC++ 6.0 the output is:
+//
+// 2 2 double double
+//
+// To fix it, write
+//
+// template <int n>
+// void f(BOOST_EXPLICIT_TEMPLATE_NON_TYPE(int, n)) { ... }
