The bootstrap script builds Boost.Build (b2) and a default 
project-config.jam file.  It doesn't really matter which compiler this 
uses (other than it selecting the same one as the default for 
project-config.jam), as long as it's one that works on your system.

If you're customising project-config.jam afterwards, just don't run 
bootstrap again, and start with running b2.
