All of them come under Boost.Math, and all are moving to C++11 in the 
next release (OK, so here and there stuff may work in C++03, but it 
won't be tested any more).

Likewise Multiprecision is moving to actively require C++11 in the next 
release.

Also Regex will deprecate C++03 in the next release - it will continue 
to work for a bit but the future is C++11.

HTH, John.
