Atually, I think a solution was given in the zsh user's guide posted
earlier:

* So, at the absolute least, you should probably surround any option
* settings in /etc/zshenv with
*   if [[ ! -o norcs ]]; then
*     ... <commands to run if NO_RCS is not set,
*          such as setting options> ...
*   fi

Put environment stuff into zshenv with the above "if"-wrapper.
