Bump version to 0.9.5
[contrib/VS2010] Fix predefined macro specification on compiler cmd line.
Revert "[examples/*c] Use _stprintf_s() instead of _snprintf()."

This reverts commit a8a7131bd4d278434d7fdd3257a25b523fc21c95.

Windows XP SP3 seems to not have the symbol sptintf_s() in MSVCRTL.DLL,
hence the examples are not working there.
