OK, I backed out the int cast I had made for dt.h.  I agree time_t
should cast to int naturally.  I noticed that HAVE_INT_TIMEZONE is
already a configure test.  Is that test not working on Cygwin?  Seems it
is working on MinGW.  The test is this:
        # ---------------------
        # Check if the global variable `timezone' exists. If so, define
        [AC_CACHE_CHECK(for int timezone, pgac_cv_var_int_timezone,
        [AC_TRY_LINK([#include <time.h>
        int res;],
          [res = timezone / 60;],
        if test x"$pgac_cv_var_int_timezone" = xyes ; then
          AC_DEFINE(HAVE_INT_TIMEZONE,, [Define to 1 if you have the global
        variable 'int timezone'.])

You can look in include/pg_config.h to see how it is defined.
