I actually don't think that there is a bug here at all. The MSVC implementations of these math functions are slightly more accurate and the glibc implementations have slightly better performance. Python 3.1.1 sets the FPU to extended precision (80 bits) on Linux, presumably to force glibc to give results that are as accurate as MSVC.[1] However, if we make Wine always set the extended precision flag before calling a glibc math function, we could see an unacceptable slowdown in programs that don't require exact values. So the only way to truly "fix the bug" would be to stop relying on glibc and instead write our own math function implementations that make the same performance/accuracy tradeoffs as the Microsoft implementations. I don't think it's worth the effort, especially since the tradeoffs that Microsoft chose could be different in different MSVC versions or on different CPU architectures. TLDR: If you need more accurate math in Wine, I recommend installing vcrun2008 or complaining to the GCC developers.
