New Revision: 85274
URL: http://svn.boost.org/trac/boost/changeset/85274

Log:
Remove BOOST_NO_EXPLICIT_FUNCTION_TEMPLATE_ARGUMENT

This makes boost::config independent of boost::core in the
modularized repos.

(from Stephen Kelly)

Daniel James: The original patch included changes for several libraries.
I'll deal with them later, they shouldn't break since the changes were to
remove code that won't be activated any more.

 // 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)) { ... }
-//
-//   template <typename T>
-//   void g(BOOST_EXPLICIT_TEMPLATE_TYPE(T)) { ... }
