Re: [Boost-build] darwin.jam vs gcc.jam

I have done more tests and a standard gcc or ConceptGCC also does not  
work with the darwin toolset with errors such as:

g++: unrecognized option '-no-cpp-precomp'
cc1plus: error: unrecognized command line option "-Wno-long-double"

We thus have two types of gcc compilers with different options:

* Apple's gcc supported by the darwin toolset
* A generic gcc, which should be but is not yet supported by the gcc  
toolset

It thus seems to me that we need both the darwin toolset and a gcc  
toolset supporting a generic gcc on MacOS X
