+If you wish to get verbose output from bjam, add '-d+2' to the invocation. Doing that, you can see that only g++ is used, and that the default compile flags are -O3. If you wish to append any other CXXFLAGS, add cxxflags="-fwhatever" to the first bjam invocation (the second invocation for install only copies the files).

+For the little it is worth, the output of bootsrap.sh is in bootstrap.log - it uses gcc without any CFLAGS, but optimizing that seems a waste of time.
