[ itch... ] Maybe we had better do something about chasing symlinks,
then. ISTM that find_my_exec could resolve a symbolic link down to the
actual executable, and then we could assume that the support files are
located relative to that. I was worried about portability but it looks
like lstat() and readlink() are defined in the Single Unix Spec ...
