Bug #13920: prepping io for stdin returns "access denied" on windows
https://bugs.ruby-lang.org/issues/13920

* Author: rocifier (Ryan O'Connor)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: 2.5.0
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
https://github.com/ruby/ruby/blob/c08f7b80889b531865e74bc5f573df8fa27f2088/io.c#L12730

`rb_stdin = prep_stdio(stdin, FMODE_READABLE, rb_cIO, "<STDIN>");`

When this line (io.c) is called upon initialising ruby with `ruby_init()` or `ruby_setup()` and the library is built with `VS2015 x86 Native Tools Command Prompt`, `fileno(stdin)` returns `-2` and `errno` is set to `13`. This raises a ruby exception and fails setup. The library has been tested with /MD and /MDd and with 2.4.2 and 2.5.0
