I ran the acinclude.m4 test manually, and it
links fine for me (altough the binary crashes
on startup).

      $ cat < foo.cpp
          /* 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;
          }
      $ g++ -fPIC -fvisibility-inlines-hidden -O0 -shared foo.cpp -o foo
      $ ./foo
      Segmentation fault

I'll try to build with those patches, thanks.
