Thanks for looking into this :)

Yes, I'm using MSVC 2013 on Windows 7.
I created a Win64 test application with the code from your stackoverflow link, and it does give the incorrect result sin(-0) = 0.
The corresponding Win32 application gives the correct result, so it seems to be a problem with the Win64 C runtime libraries.
