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?
