 I installed gcc 4.7 from macports and added the following to my user-
 config.jam:

 {{{
 using darwin
     : 4.7
     : /opt/local/bin/g++-mp-4.7
     ;
 }}}

 Now when I run

 {{{ $ b2 darwin-4.7 }}}

 , the build process will stop at compilation stage because of an error:

 {{{ g++-mp-4.7: error: unrecognized command line option '-no-cpp-precomp'
 }}}

 `-no-cpp-precomp` was already unrecognized in darwin-4.4, but then it only
 caused a warning without further obstructing the build process. I don't
 know at what version of darwin-gcc this changed into an error.

 If I repeat the displayed command without the `-no-cpp-precomp` option it
 works fine. Linking also works without errors.
