"autoload -U" expanding alias

[Thorsten Kampe <thorsten@xxxxxxxxxxxxxxxx>]

[zsh 4.2.0 on Gentoo]

I have a script that zcompiles some rcfiles. It's asking whether to
overwrite files:
re-compiling /home/thorsten/.zsh/.zlogout.zwc: mv: overwrite
`/home/thorsten/.zsh/.zlogout.zwc.old', overriding mode 0400? 

What's happening and how can I prevent this question?

The "-U" keeps my "mv -i" alias from being expanded....
