support nanosec file timestamp on newer Windows

2017-12-04T10:48:30+00:00

Support nanosec file timestamp on Windows 8 or later.
Original patches are written by kubo (Kubo Takehiro).
Windows 7 and earlier also supports nanosec file timestamp, but it's too
accurate than system time.  so, this feature is disabled on such versions.
[Feature #13726]

this change also includes [Misc #13702]

Suppress a warning in ruby/win32.h [Fix GH-1591]

2017-04-21T00:11:56+00:00

Fix a warning in ruby/win32.h which can cause failures with mkmf

The return value is implicit type casted from 'long double' to 'double', currently.
This causes a gcc warning like this:

```
In file included from C:\Ruby24-x64\include\ruby-2.4.0/ruby/defines.h:243:0,
                 from C:\Ruby24-x64\include\ruby-2.4.0/ruby/ruby.h:36,
                 from C:\Ruby24-x64\include\ruby-2.4.0/ruby.h:33,
                 from conftest.c:1:
C:\Ruby24-x64\include\ruby-2.4.0/ruby/win32.h: In function 'rb_w32_pow':
C:\Ruby24-x64\include\ruby-2.4.0/ruby/win32.h:786:12: warning: conversion to 'double' from 'long double' may alter its value [-Wfloat-conversion]
     return powl(x, y);
            ^~~~~~~~~~
```

This is fixed by the attached explicit type cast.

Moreover when CFLAGS is set to '-Wconversion', it prevents the compiler from
building. This is the case at the nokogiri gem.

The original issue arose at RubyInstaller2: https://github.com/oneclick/rubyinstaller2/commit/576a0eb70aa9348b366c3ecfe83c67811b7bcb9b
