How common is :: in makefiles

[Mats L|fkvist]

I could find it even in an old set of V7 manuals, not in the man-page but in
the separate article about make (on newer systems as Pyramid OS and Sun OS it
is also mentioned in the man-page). Does the V.3.2 documentation include ANY of
the articles from "Volume 2" of the Unix manuals (lex, yacc, vi, {nt}roff etc)?
If not, the are probably available at extra cost :-)
