I had an issue with TBB's 'version_string.tmp' file on a Windows platform.
The file was deleted by Windows Disk Cleanup utility because it has extension 'tmp' and the TBB build was broken:
..\\tbb40\\src\\tbb\\tbb_version.h(36) : fatal error C1083: Cannot open include file: 'version_string.tmp': No such file or directory
Since the file is used in the build process I would consider renaming it. Extensions like 'hxx', 'txx' or 'ver' could be considered instead.
PS: I recovered the file from a backup archive.
