Subject: fix broken sysconf when correct value is -1
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=c61312596608bf819b693c04a395f1b4e3e0acf0;hp=c5d1adc56c22ead8caa9effcee0518a7a8ff3c06

fix broken sysconf when correct value is -1

this caused glib to try to allocate >2gb for getpwnam_r, and probably
numerous other problems.
