Hi Noel,
I think the simple way is to use "MATCH rule". Something like this:

  local compiler_basename = $(command[1]:B) ;

  local m = [ MATCH (.*)CC(.*) : $(compiler_basename) ] ;
  local new_basename = $(m[1])cc$(m[2]) ;

  command_c = $(command[1--2]) $(command[-1]:B=$(new_basename)) ;

Let me know if this works for you. If yes, we can adjust sun.jam that's in 
CVS.
