As long as you're only doing this within cppsourcecodeoperation.cpp and
friends then that's fine.
BTW,  to identify a destructor in several places you write something like
   ... methodName.find(i18n("~")) ...
That i18n() is superfluous - the tilde is part of the C++ syntax and as such
should not be localized?
Also some documentation of the arguments of applyStereotypes() in
cppheadercodeoperation.h wouldn't hurt.

IMHO that's fine - If nobody objects then I'll commit it.

I believe it could be okay as long as you're only doing this inside the
<codegeneration> part of <XMI.extension>, but I haven't tested it yet.
(I.e. I haven't yet changed the "#if 0" in ClassifierCodeDocument::
saveToXMI() into "#if 1")

Haven't tried it yet.

One thing - I notice that when using the old C++ generator (see the checkbox
in General Settings/Miscellaneous) a constructor is generated twice, one with
"void" in front and one without.

I'm appending the diff against current svn trunk with some minor changes.
I was in the directory kdesdk/umbrello/umbrello when making this diff.
Please send your patches as proper text attachments or gzipped -
I had a hard time cutting and pasting the diff from your mail.
