[boost] [intrusive] Problem with EDG base compilers in strict Ansi mode.

Hello,

currently any_test and doc_any_hook fail on Tru64/CXX with the following 
errors:

cxx: Error: ../boost/intrusive/detail/any_node_and_algorithms.hpp, line 
276: class template "boost::intrusive::any_algorithms<VoidPointer>" has no 
member "unlink_not_available_for_any_hooks"
           (notmember)
       any_algorithms<VoidPointer>::unlink_not_available_for_any_hooks();
-----------------------------------^
cxx: Error: ../boost/intrusive/detail/any_node_and_algorithms.hpp, line 
283: class template "boost::intrusive::any_algorithms<VoidPointer>" has no 
member "swap_nodes_not_available_for_any_hooks"
           (notmember)
       any_algorithms<VoidPointer>::swap_nodes_not_available_for_any_hooks();
-----------------------------------^

AFAICT this is the only EDG based compiler which tests in strict Ansi mode, 
adding -strict_ansi to the other EDG based compilers (acc for example) 
would probably lead to the same error.

Attached patch contains a proposed fix for this. It checks for __EDG__ and 
__STD_STRICT_ANSI to enable the fix and works for me locally.

The patch should replace the compile error by a link error, because in 
strict Ansi mode EDG doesn't allow you to refer to non-existing names.

OK to apply?

Regards,
Markus
