suppose the host already has ada  (eg it  has say gcc-4.4.x with ada and I 
want  to build a toolchain with gcc-4.5,x or gcc-4.6.x  with  ada enabled;  
can this be done?  And if so how so )

(Though strictly speaking slightly off topic how is this  extended to  
gfortran  i.e. those who want to build gfortran in the toolchain as well ) { 
When I made a half-hearted  attempt  some time ago  by adding  fortran  to --
enable-languages="c,c++,fortran" in the final gcc compilation it compiled   
but I was unable to install it }
