QA Risk Assessment Reason:ruby API issue; should be covered in unit tests
I was investigating why David Schmitt and I were getting different results from `Puppet::FileSystem.symlink` on Windows. His VM was correctly reporting an error and mine was silently failing.
When run as a non-administrator user on my VM, `CreateSymbolicLinkW` would return non-zero (success for this function) when it should have failed. Going through the MSDN docs, I noticed that it returns a 1 byte `BOOLEAN` rather than the 4 byte `BOOL` that it is currently prototyped for with FFI (so I was getting a value with random data in the 3 upper bytes).
Changing the FFI prototype for the function over to returning an `int8` resolved the problem for me (see linked PR).
