Yes, in KDE3 we had the following:

        AC_TRY_LINK(
        [
          /* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19664 */
          #include <string>
          int some_function( void ) __attribute__ 
((visibility("default")));
          int some_function( void )
          {
            std::string s("blafasel");
            return 0;
          }
        ], [/* elvis is alive */],
        kde_cv_val_gcc_visibility_bug=no, 
kde_cv_val_gcc_visibility_bug=yes)

That's the test that enabled -fvisibility-inlines-hidden and that was not 
ported to CMake.

My question is: is the test necessary or does gcc 4.1.0 already 
incorporate the fix?
