The problem is in Boost.Build's handling of
static libraries (In some cases, static libraries
can be propagated upwards too far):

You can work around this with something like:

class kill-usage-requirements : alias-target-class
{
    import property-set ;
    rule compute-usage-requirements ( subvariant )
    {
        return [ property-set.empty ] ;
    }
}

import project ;
import targets ;
rule my-alias ( name : sources + )
{
  return [ targets.create-metatarget kill-usage-requirements
    : [ project.current ] : $(name) : $(sources) ] ;
}

my-alias text-to-c : text-to-c//text-to-c ;

I've made a reduced test case for this that
works with any toolset.  I'm not exactly
sure how to go about fixing it yet, though.
