I was going to write "that way lies madness" as a response before having read
your whole message, but apparently that was drummed in sub-conciously.

It just doesn't seem like a good idea to wriggle around like that, changing
protected for public. I looks to me like a bit of ugliness that is just asking
for maintainence trouble.
But in this particular case I'd like to doubt Thiago's words: template friends
are documented to work in MSVC , IBM XL C++ . I may be missing a
subtlety here, though. I haven't actually tried compiling KSharedPtr with the
earlier proposed patch in Sun Studio, though. I'll try it in the morning.
Suffice to say the proposed workaround doesn't seem nice at all to me. Don't
forget that the range of KDE-supported compilers is smaller than the range of
Qt supported compilers (right?) so we need to just check those -- and the C++
standard. A quick search didn't turn up any chapter and verse saying you can't
have template friends.
