New Revision: 195969
URL: http://svn.freebsd.org/changeset/base/195969
Log:
Preset errno to zero before calling strtol(), so the check afterwards will
be valid. This is required since the malloc call from r195859 leaves
errno in an unknown state.
For STABLE-7 only, as CURRENT doesn't make this strtol call.
