Test D03 hang under cygwin 1.7

[Vin Shelton <acs@alumni.princeton.edu>]

Hello -

Under the soon-to-be-released Cygwin 1.7, I downloaded the latest CVS
sources and ran a build from scratch.  I'm getting a test hang in D03:

ZTST_verbose=3 make TESTNUM=D03 check
cd Test ; make check

        fi
if ZTST_testlist="`for f in /usr/local/src/zsh-2009-02-05/Test/D03*.ztst; \

        rm -rf Modules .zcompdump; \
        exit $stat
