gcc+binutils+gmp+mpfr in /src 
 (4.3.1, 2.18, whatever)  


  build=i686-pc-cygwin  


  mkdir /obj/native  
  cd /obj/native

install  


  mkdir /obj/cross  
  cd /obj/cross

Something to do with Canadian cross not being cross -- if target == host, but
host != build. Builds needs to discern between building a cross compiler vs.
cross building a native compiler, vs. perhaps cross building a cross compiler.
