And another thing....

Ran "bjam -a headers" from the root directory to force the headers to be 
rebuilt, and the tests now build and pass OK... except that's a mistake 
because I see that old test results that depend on those headers were *not* 
rebuilt.  So you need to bjam -a from the libs/mylib/test directory as well 
whenever you change branches :-(
