That's what I was trying to tell you.  If you remove
the backslashes, then the $(awk ...) runs at the time
that you *define* the compctl, rather than at the time
that you attempt a completion.  That's the effect of
having it inside double quotes.  So without the
backslashes, it only "works" if you run the compctl
command in the same directory that holds the Makefile.

Furthermore, with the backslashes present, they should
be getting removed by zsh at the time it parses the
double quoted string, long before awk gets anywhere
near it.  The whole thing with the backslashed dollar
signs is a wild goose chase; the problem is somewhere
else, and it's almost certainly something to do with
awk.

After loading the new system with `compinit', unset
the elements of the _comps assoc corresponding to the
compctls that you prefer to use.  E.g.

 unset '_comps[foo]' '_comps[bar]' '_comps[etc]'

or (shorthand)

 noglob unset _comps[{foo,bar,etc}]

There isn't any automated way, but it's possible that
there are zstyle commands you could use to get the
behavior that you want -- many of the new completions
are very configurable.  Ask on the list about a few
that are most important to you.  Even if zstyles are
not available it's possible that your different
behaviors are generally useful enough to get folded
into the distribution.
