Hi Robert,
I have a problem with the SunOS CC.
It does not like that the prototype of ClipNode::setStateSetModes() differs
from implementation of that function in the constness of the second
parameter.
On SunOS it compiles fine, but I get link errors when the variant that is
declared in the header is referenced.
The attached src/osg/ClipNode.cpp file removes the const qualifier from the
implementation to match exactly the prototype in the header file.
The file is based on revision 7386 as of today.
Please apply.
Greetings
Mathias
