The third edition of the SVID includes both the mkfifo() function and
the mkfifo utility.  These are also in the POSIX 1003.1 and 1003.2
standards, respectively, so future OS releases from all vendors that
conform to POSIX and to X/Open guidelines will have them.

Vanilla 4.3 BSD doesn't have either mkfifo() or mkfifo.
