    _______________________________________________________

Details:

POSIX requires that -prune shall always evaluate as true.  However, GNU find
currently evaluates it as false if -depth is in effect.

Contrast this example between Solaris and GNU:

$ mkdir tmp
$ cd tmp
$ mkdir a
$ touch a/f
$ find . -depth -name a -prune -o -print
./a/f
./a
.
$ /usr/xpg4/bin/find . -depth -name a -prune -o -print 
./a/f
.
