Subject: [boost] [config] BOOST_NO_SFINAE_EXPR and GCC 4.6.4

According to this table http://gcc.gnu.org/projects/cxx0x.html, GCC
supports "Solving the SFINAE problem for expressions" since 4.4.
According to Boost.Config, it is since 4.5. The following test case
works fine with 4.8.1, but fails miserably with 4.6.4:

Errors include invalid conversion from X const* to X*, and use of
non-member-ptr in member-ptr expression. GCC 4.7.3 (tested by zao at
#boost) shows similar results: https://www.acc.umu.se/~zao/kbsfinae11.txt
Should BOOST_NO_SFINAE_EXPR be adjusted according to the results of this
test case?
