Subject: Re: bug#9544: 24.0.50; cc-mode does not indent Qt class correctly

This seems to work fine out of the box for me in Emacs 25.

Reading the manual, if you have further problems, the variable
c-macro-names-with-semicolon should help (see the info node about this:
"Macros with ;").  I'm closing this as unreproducible, but please update
if both Emacs 25 and this variable fail to solve the issue.
