Subject: [ruby-dev:50754] [Ruby trunk Bug#15465] Tests failed on i386-cygwin

Issue #15465 has been updated by fd0 (Daisuke Fujimura).


In case of `make btest`,  test_massign.rb and test_thread.rb succeeded.

The cause of failures is environment variable `RUBY_FIBER_MACHINE_STACK_SIZE=1` in tools/runruby.rb.

The workaround (not beautiful) is as follows:

```diff

 runner = File.join(abs_archdir, "exe/ruby#{config['EXEEXT']}")
 runner = nil unless File.exist?(runner)
```
