that's the warning I get when compiling src/sdk/scripting/sqplus/SqPlus.cpp with gcc 4.3. It's rev5382.

inlined from 'SQInteger SqPlus::getVar(StackHandler&, SqPlus::VarRef*, void*)' at SqPlus.cpp:178:

Because of this the package doesn't get published for suse 11.1 in my repository on the buildservice (a check for this type of warning has been added).
