test/ruby/test_exception.rb on Windows.
wrap by __try and __exception statements on mswin to raise SIGSEGV
when EXCEPTION_STACK_OVERFLOW is occurred, because MSVCRT doesn't
handle the exception.
however, (1) mingw-gcc doesn't support __try and __exception
statements, and (2) we cannot retry SystemStackError after this
change yet (maybe crashed) because SEH and longjmp() are too
uncongenial.
* signal.c (check_stack_overflow, CHECK_STACK_OVERFLOW): now defined on
Windows, too.
