Thanks for the help, I searched but didn't find modentry.c. (This file
calls `boot_' and `cleanup_', how is this turned into `boot_foo' and
`cleanup_foo'??)
Anyway, this might indeed require that we make setup and finish

separate mail.

This doesn't happen for me, are you sure that you haven't configured
deltochar to be statically included in zsh?
