SysTempFileName on Unix-like platforms now behaves identically to SysTempFileName on Windows. It no longer uses only the first five characters of the file name part of the template, appending a random string to make it unique. It also no more prepends an operating system-chosen writable path if no path is given in the template. Instead it now uses the same filler-based mechanism as the Windows version does.

Existing ooRexx programs using SysTempFileName on Unix-like platforms will need to be amended.
