Yes I did.  It doesn't work (yet).  One step at a time.

There is a TCL regular expression that needs tweaking.  
I may even have fixed the g77 driver.  Let's see - yes:

	* lib/prune.exp: Remove "In (program|subroutine"block-data)"

	* lib/g77-dg.exp: Trim g77 error messages so that they are
	recognized by dg.exp.
