A little experimenting got me to the point where I could generate the
error message.

Take this source, which confuses unformatted and formatted I/O (in that
order):

toon@laptop:~/g77-bugs$ cat howarth.f
      dimension ur(3)
      open(unit=13)
      read(unit=13,*) ur(1), ur(2), ur(3)
      end
toon@laptop:~/g77-bugs$ g77 howarth.f
howarth.f: In program `MAIN__':
howarth.f:3: 
         read(unit=13,*) ur(1), ur(2), ur(3)
                      ^
Invalid form for READ statement at (^)

Note that the ^ points to the format string (*) as invalid.
