| Yes, indeed. I woud like to get it fixed, gfortran should move to the
| generic GCC diagnostics machinery. "hopefully for GCC 4.1", to quote

Positioning (1) as you currently do can be achieved through the
callback BEGIN_DIAGNOSTIC, which output any necessary bits before the
main diagnostic text is emitted.  

(The C++ front-end, for example, uses it to print the stack of  template
instantiation contexts).
