Subject: Cleanup isdigit() warnings.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=be2c418b73fcb6c606725d84c18b0ad618082c75;p=openvswitch

Cleanup isdigit() warnings.

NetBSD's gcc complains if isdigit()'s argument is an unadorned char.  This
provides an appropriate cast.
