ld -o behaviour

[Ben Elliston]

Hi Nick,

   : ld behaves inconsistently with its `-o' option.  If I run:
   : 	ld foo.o -o foo.x  or
   : 	ld foo.o -ofoo.x
   : I get the same results.  If I run:
   : 	ld foo.o -omagic
   : ld names the output file `a.out' (as if no -o option was given at all).
   : Could it be that ld accepts -omagic is if it were --omagic?

   So the linker is being consistent, just a little unintuitive is all.

One could argue this is a bug -- GCC passes the `-o' option given by a user
on the command line straight to `ld', leading to the inconsistent behaviour
I described.

Accepting single dashed long arguments is probably wrong.  What was the
justification?

Cheers, Ben
