[Message part 1 (text/plain, inline)]

I found a bug in arc-mode.el which makes it unable to open zip files, on
further analysis i found it was using incf instead of cl-incf. It is now
able to open .zip files and works as expected. I have attached a patch that fixes it.

Thanks, but where did you get the version of arc-mode,el which uses
incf?  The version included with Emacs 30.1.90 uses cl-incf, not incf.

I was working on another patch on the master branch of emacs, and while testing i encountered this, but after digging and a quick magit blame I realised this is one of the changes of emacs master branch, I should have tested my changes after building emacs instead of relying on my unstable emacs, my bad!

OK, thanks.  Now it's clear.  We indeed made this change on the master
branch, where incf is a macro.

So I'm closing this bug.
