I am using bjam 3.1.17 on MacOS 10.5.6, and when I try to use the GCC  
4.2 compiler installed by Xcode (Apple's development environment), it  
gives me this error:

cc1plus: error: unrecognized command line option "-Wno-long-double"

This happens whether I am using the version of boost.build that is  
bundled with boost 1.37.0 or the version that is current on the  
boost.build web site.

A similar problem occurs when I use bjam 3.1.17 on MacOS 10.5.6 with  
the GCC 4.0 compiler.  In this case the error message is this:

cc1plus: error: unrecognized command line option "-fcoalesce-templates"

This does not happen with the version of boost.build that is current  
on the boost.build web site, but it does happen when I am using the  
version that is bundled with boost 1.37.0 (which I understand is the  
newer version).
