/* 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.
