	Though it was added somewhat recently:

- --cut: coreutils-8.5/NEWS --
* Noteworthy changes in release 6.9.90 (2007-12-01) [beta]

** New programs

…

  mktemp: create a temporary file or directory (or names)
- --cut: coreutils-8.5/NEWS --

	In particular, Debian 5.0 (Lenny, current oldstable) shipped
	mktemp(1) separately from GNU Coreutils [1]

	And what's about GNU/kFreeBSD and GNU/Hurd, I wonder?

	Well, supporting a single system preasumably requires less
	effort than supporting many.  On the other hand, I doubt that
	there's a free software package whose maintainers will oppose
	any volunteers' effort to improve portability.

	If seen this way, it appears that it's the lack of such
	volunteers that makes software non-portable.
