emerge of kdelibs fails with "2 overloads have similar conversions"

[Thomas Fischer]

Hello,

I am trying to emerge kdelibs, but it fails at 70%
with the following output:


ls w[ 70%] Building CXX object khtml/CMakeFiles/khtml.dir/xpath/parser.obj

        note: qualification adjustment (const/volatile) may be causing the ambiguity

Any ideas how to fix this? I guess the original
developer used gcc and a different interpretation
of operators and overloading compared to msvc...

How to proceed here?

Thanks in advance!
