[csw-maintainers] gar problem building zsh

[Oliver Kiddle]

I get the following error building zsh in gar:
/bin/sh: syntax error at line 3: `;' unexpected

This is coming from this line in gar.lib.mk:
                ( for i in $(filter %/$*,$(URLS)); do  \
URLS does not contain anything matching %/CSWzsh.gspec so the for loop
is being passed an empty list.

Any idea what broke this and how to fix it. I'd like to update zsh
to 4.3.11.
