Hang on - you say that you are getting this message during *linking* ? 
The error message comes from the compiler, not the linker, so why is it 
turning up in the linker's output ?  Do you have LTO enabled ?  (If you 
do, does disabling LTO make the problem go away ?)

Also, if you add -Wno-attributes to the command line, does the problem 
go away ?  (I assume that you are not otherwise using unsupported 
attributes, so disabling the warning would not be a big issue).  Just a 
thought - I know that this is not a real solution to the problem.

I hate these kinds of bugs. :-{

Are there any clues as to where the compiler/linker thinks that the 
visibility attribute is being used ?
