cc ignores the -o flag when -c is present

Hmmm, just like my reply of several days ago seems to have disappeared.
This is turning out to be a jinxed thread.

If you want to mail to me, you must do as I .sig, not as I From:.  IBM
Austin is actually getting an internet connection, but I'll be long gone
before then.

You're completely right about the Sun; I screwed up by doing "-o f/foo",
which is how I'm used to using -o, and the Sun complains about that.

But the point remains: other systems definitely have trouble with this
combination of flags, so why not do it portably instead?

I guess your comment about "IBM screwing up again" sounded like it to me;
but I should have had a couple of :-)'s sprinkled around that reply, so
please don't take it too seriously.

Nope.  "cc && mv" is portable, but using the -o flag to stick the .o file
somewhere isn't.
