[boost] [config] Variadic template macros in gcc header

Why is there two mutually exclusive macros indicating variadic template 
support for gcc ?

There is the established BOOST_NO_VARIADIC_TEMPLATES which says that any 
compiler does not have variadic template support. Then I find that for 
gcc there is also BOOST_HAS_VARIADIC_TMPL which evidently says that the 
compiler does have variadic template support, and is in no other 
compiler header file than the gcc one. Since the two config macros are 
mutually exclusive in the gcc header file, why is there any need for 
BOOST_HAS_VARIADIC_TMPL ?
