ld -o behaviour

[Ben Elliston]

Hi Nick,

   Note - there is still a problem if the user decides to call their
   executable 'utput' since "gcc -output foo.c" will collide with the
   -output linker switch...

Yes, you're right.  In this case, I think it would be reasonable to only
accept --output (and not the single-dash version).  What do you think?

   Any objections to this patch ?

Looks good to me.  Let's hope the change in command line syntax doesn't
upset too many people!

Ben
