I struggling with boost.build for a while and I don't get the Jamfile 
working. I hope you are so kind to help me a little bit.

I use target alternatives for different platforms. The alternatives 
depend on used compiler, architecture, target-os and linkage.

I've added a new feature ctxapi which is used to select the correct 
target-alternative.

Unfortunately the rule setting the default value for ctxapi can not 
access the properties like <toolset>.

rule default_ctxapi ( properties * )
{
    if <toolset>gcc in $(properties)
    {
      # never entered ?!
    }
}

feature.set-default ctxapi : [ default_ctxapi $(properties) ] ;

I didn't found a hint inside the documentation.
