What is 'markfile' in the default make ruleset?

[Colossus @ The Forbin Project]

  Can anyone give me the reason behind the built-in dependency in make
for the file 'markfile'?  It seems that markfile is dependent on
markfile.o, and the command list tries to find the SCCS id lines
and generate an object module?!  If anyone can shed some light on this
for me, I'd appreciate it.

  Also, there appears to be a '-g' option (undocumented, of course :-)
which automagically attempts an SCCS 'get' on a dependent when none of
the rules are satisfied.  Is there any information on this either?
