If you really must know..

1. Don't use std::locale-support in the test libs.

2. Remove code that needs std::locale from Boost.Test.

I know that second one might seem draconian, but I've been looking at 
how to fix it at the BBv1 level, and I don't think it's possible. To 
allow having that std::locale-support requirement on the test libs means 
  changing *every* Jamfile that references the test libs to also have 
the std::locale-support requirement. Which means that if every test we 
have uses one of the Boost.Test libraries then *every* test that uses a 
DLL will break for CodeWarrior.

I have a question..

Is std::locale support really required by Boost.Test?
