Bug#1097663: Works for Me

[Barak A. Pearlmutter]

I don't know how to fix this because it compiles fine for me, just now. It
looks like there's now a more recent version of qmake6 etc, maybe that
fixed it? Or updates so now the moc_ file generation avoids the duplicate
definition? Anyway I'm not sure what I can do when it compiles fine for me
with CC=gcc-15 CXX=g++-15. Is there some fancier thing I should try to get
it to fail?
