[PATCH] Fix compiler warning about `abs'

[Zach Davis]

Hello all-

I recently compiled master with clang, and it pointed out a warning
about abs/labs.

I wasn't able to force a bug from the warning, but it was an easy enough fix.

Zach

Subject: [PATCH] Fix compiler warning about `abs'

Clang noted that `labs' should be used instead of `abs' for longs.

* libguile/numbers.c (log_of_fraction): Use labs instead of abs.
