[Dovecot] Problem with configure.in in dovecot-stable CVS

I am having trouble with using dovecot-stable from CVS. I get the following error when running autogen.sh:

configure.in: 4: required file `./[config.h].in' not found

I see the config.h.in file in the root dir, but I cannot figure out what the brackets are for. If I modify the file and remove the brackets, it works properly and I can compile dovecot.

What are the brackets in the name for? Am I breaking something by removing them?

Thanks,
