Well, we only have xmms in BLFS and it is out of date.  They just
released a new xmms last week (after four years).

I was curious and looked at the xmms source for both 1.2.10 and 1.2.11,
but a grep couldn't find a use of abs() times a negative constant in either.

I do think we need to put a patch and an errata comment out on LFS 6.3
though.
