[boost] Request for small test in VC7.1

I'd appreciate if someone on the list could try the following in VC7.1 and report the results: template<typename T> struct A { template<typename Q> void operator()(const Q&){} }; template<typename T> struct B: private A<T> { using A<T>::operator(); }; int main() { B<char> b; b(3); return 0; } The regression tests for multi_index seem to indicate that VC7.1 is having trouble with this kind of construct and I'd like to make sure before applying any fix. Curiously enough, this problem also shows up in GCC for versions under 3.4, as confirmed in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=9810 Thanks, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
