I believe Tobi has done some work on it recently, so you should coordinate 
with him.

We also need a fortran.dg testsuite. In fact several of the existing tests 
should be using the dg test harness, not torture.

If/when we do start running the g77 testsuite we want to do it selectively. 

Tests that should work, but don't, should be XFAILed, bugs filed and the PR 
noted in the testcase.

Tests for unimplemented features should be disabled/marked as unsupported. I 
guess a README file or similar will be more convent for keeping track of 
these than a monster meta-bug.
