CC Mode: Prevent over-eager recognition of a variable as a found type
This fixes bug #59233. It occurred in the C source code fragment
open_replies = alloca (nproviders )
, where typing a * before the closing parenthesis caused nproviders to be
prematurely recognized as a type.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): CASE 18 - set
unsafe-maybe to t, when needed.
