If you don't want it to link, you need the flag `-c'.  GCC doesn't care what
extension its output is given; the other flags determine which stages are
executed (and the _input_ file extensions).

And the floating point error occurs while linking a file you don't want to
link. :-)  The only reason I can think of for that is a possible version
conflict.  You've upgraded everything to 1.12, right?

The machine I had to run stacker on wasn't one I wanted to run DJGPP on
(386SX/20 w/2M RAM), but I don't recall it causing that sort of problem.
