Hi Mark,
my understanding is that : was replaced by :: to force regeneration
of the depend file on every make invocation as described here
http://www.gnu.org/software/autoconf/manual/make/Double_002dColon.html
On the other hand, the 'depend' target is not listed as a prerequisite
of any other target; I would therefore add
Makefile: depend
line and leave :: in place. I would also not regenerate depend on 'clean'.
Best,
Volodymyr
