Ah, good point.  I just noticed two "gfortran"s in the list, so 
something is funny.  Let me try...

Yes, so g77 comes up first.  I take it from the epilogue comment that 
the issue isn't compile errors, but the compiled code will malfunction. 
 So "fixing compile errors" isn't a good strategy in that case.

Now that I understand the autotools a little more, I don't see the 
epilogue as much of an issue.  Someone can always set F77 environment 
variable to g77 if that is wanted.

So where were we?  If we simply remove FC=$F77, then worry about compile 
errors?
