If that's the case, the best thing to do for someone building g77 + GNAT 
together is to disregard the g77 backend patch alltogether (note: from 
g77-0.5.21 onwards !).  That will give you a Fortran compiler that produces 
suboptimal objects, but they will be as correct as can be, and the Ada 
compiler isn't compromised (which is the whole point of using Ada).

You are right that the "fix" to the g77 frontend is trivial if you know what 
you're doing, but we have already one bug report from a g77 user who tried to 
do it on his own (just in because of the gnu.ai.mit.edu unreachability) and 
it shows it's hard if you don't know what you're doing ;-)

Sorry to be so vague about 2.7.2.3 - I simply haven't got the time yet to 
look at it (nor the disk space) ....
