empty zsh prompt string under Cygwin 1.1.0 xterm

[Eric De Mund <ead@xxxxxxxxx>]

Folks,

My zsh has a null, empty prompt (nor are my .z* files sourced) when I
bring up a zsh xterm:

--------CUT HERE--------
ls -aCF
./              .emacs~         .zshenv~        doc/            out
../             .ncftp/         .zshrc          is-docs/        scratch/
.bash_history   .zlogin         VisualCafe/     jdk-1.2.2_005/  sw/
.bash_profile   .zlogout        archive/        lib/            tmp/
.emacs          .zshenv         bin/            nohup.out
echo dog
dog
cd ..
ls -aCF
./              ../             Administrator/  ead/

Is this a zsh or Cygwin FAQ? I wasn't able to find it in either archive.
I get the same behavior when I invoke rxvt(1) instead of xterm(1). (And
it *aggravates*.) My environment is:

Need I update my X clients? Or is this simply a matter of me missing
some environment variable? When rxvt(1) comes up, the TERM type is even
xterm-color.

Please advise.

Thanks,
Eric
