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:
# PGAC_VAR_INT_TIMEZONE
# ---------------------
# Check if the global variable `timezone' exists. If so, define
# HAVE_INT_TIMEZONE.
AC_DEFUN([PGAC_VAR_INT_TIMEZONE],
[AC_CACHE_CHECK(for int timezone, pgac_cv_var_int_timezone,
[AC_TRY_LINK([#include <time.h>
int res;],
[res = timezone / 60;],
[pgac_cv_var_int_timezone=yes],
[pgac_cv_var_int_timezone=no])])
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'.])
fi])# PGAC_VAR_INT_TIMEZONE
You can look in include/pg_config.h to see how it is defined.
