#include "Driver_xst.h"
# Historically dbd_db_do4, dbd_st_execute, and dbd_st_rows returned an 'int' type.
# That's only 32 bits (31+sign) so isn't sufficient for very large row counts
# So now instead of defining those macros, drivers can define dbd_db_do4_iv,
# dbd_st_execute_iv, and dbd_st_rows_iv to be the names of functions that
# return an 'IV' type. They could also set DBIc_ROW_COUNT(imp_sth).
#
# To save a mess of #ifdef's we arrange for dbd_st_execute (etc) to work
# as dbd_st_execute_iv if that's defined
#
#if defined(dbd_st_execute_iv)
#undef dbd_st_execute
#define dbd_st_execute dbd_st_execute_iv
