[Bug target/25960] __gcc_add doesn't handle -0.0L properly

------- Comment #4 from amodra at bigpond dot net dot au  2006-02-02 04:30 -------
I don't think this bug should have been closed so quickly.  Fixing __gcc_qadd
to properly handle a -0 result is trivial, and only costs one extra compare and
branch.  The multiply and divide support in darwin-ldouble.c already have
special code for -0, with a comment "Preserve -0", so I think lack of such a
test in __gcc_qadd is simply an oversight.
