Subject: fix unused variable warnings in new nextafter/nexttoward code
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=4e597feef0595caefa39ab43c813734a1244fa84;hp=4e597feef0595caefa39ab43c813734a1244fa84

fix unused variable warnings in new nextafter/nexttoward code

apparently initializing a variable is not "using" it but assigning to
it is "using" it. i don't really like this fix, but it's better than
trying to make a bigger cleanup just before a release, and it should
work fine (tested against nsz's math tests).
