// Bug: g++ was failing to destroy C<int>::a because it was using two
// different sentry variables for construction and destruction.
//
// Some targets (e.g. those with "set_board_info needs_status_wrapper 1"
// in their dejagnu baseboard description) require that the status is
// final when exit is entered (or main returns), and not "overruled" by a
// destructor calling _exit.  It's not really worth it to handle that.
// Skip if target: mmix-knuth-mmixware xtensa-*-elf*
