	Sounds reasonable to me...so you want the test changed to:

===========================================================================
#include <stdio.h>
#include <time.h>

main() { struct tm *tmstruct; printf("%s\n", tmstruct->timezone); }
===========================================================================

	And, if the compile fails...how is HAVE_INT_TIMEZONE set?  to
FALSE?
