/* Some versions of glibc 2.7 has a bug in strtok_r when with optimization that
 * can cause segfaults:
 *      http://sources.redhat.com/bugzilla/show_bug.cgi?id=5614.
 *
 * Open vSwitch works around this problem by supplying a replacement string.h.
 * This test program verifies that the workaround is in place.
