[Bug libstdc++/19664] libstdc++ headers should have pop/push of the visibility around the declarations
------- Comment #104 from funtoos at yahoo dot com 2007-05-28 04:15 -------
kdelibs doesn't link with gcc-4.2.0 with hidden visibility. It compiles and
links fine with gcc 4.1.2 with patch from Comment #86. That patch was included
by gentoo till 4.1.2 and dropped because this bug is supposedly fixed in 4.2.0.
I am having difficulty understanding it. How is it fixed if it doesn't even
match the functionality provided by one of the earlier proposed patches? Or Is
it that the kdelibs-3.5.[67] code needs to change for the new patch in GCC
4.2.0? Where is the problem?
The message from kdelibs link is:
