This is a bit confussing...
lets sum up the background story:
- kjs(/wtf) loves gcc features
- kjs-cmake filters out (gcc) pedantic
now comes the problem... whats with other compilers?
if you look at the commit message that caused the warnings:
"According to CPP standards (defined(X) && X) should be the same of just (X). On the \
other hand it is undefined behavior if 'defined' appears in a macro expansion. gcc \
-pedantic and icl evaluates them always to false." ( \
http://quickgit.kde.org/?p=kdelibs.git&a=commit&h=75fa90c16232186bbd287a2ac79839ea34da32c4 \
)
-> "it is undefined behavior if 'defined' appears in a macro expansion" <-
So? Whats the correct solution here?
And yes, I agree the warnings ARE annoying.
But I would like to hear a second opinion here :)
