The fix is on the code path for all platforms, so running the test on all 
platforms could help catch future regressions.  There could also be unusual 
cases, such as cross compiling for Linux on Windows, and thus you could have 
Windows-style paths even though the target is Posix.  Or someone might further 
refine the fix to make more cases work correctly for mingw but inadvertently 
cause problems for other platforms.
