incf not implemented

[Mark A. Hershberger]

From starting gnus after M-x toggle-debug-on-error RET, this backtrace:

Debugger entered--Lisp error: (invalid-function incf)
  incf(0)

Did we remove it? Or are you using a newer version of gnus? The remacs code is an early 26.

incf is an alias of cl-incf defined in cl.el

In any case, opening gnus now works. Both when started with -q --no-site-file and when used with my config.
