It appears to me that the sample configuration file (the default install's /etc/hostapd.conf, that you apparently replaced with your own after doing a clean install, and prompting this thread), has been unchanged since February 2007.

I don't use hostapd. I've just looked at the man page. And it seems to me that:

Your first error is an apparent macro assignment and is attempting to using the reserved word "interface".

Your second line doesn't produce an error message, instead it assignes the macro "driver" and then never uses it.

And so on... repetitively, through the rest of the file.

Because you have destroyed your sample hostapd.conf file, I will replicate it here, so that you may copy/paste/edit as needed.
