The symbol is present in libstdc++.so.6.0.9 and libstdc++.so.6.0.10, but not in libstdc++.so.6.0.8 or libstdc++.so.6.0.11. > * I have changed the glibc hppa-linux-gnu port to define > __NO_LONG_DOUBLE_MATH, > and therefore the signbit macro, even in the abscense of optimization, will > always return a valid signbit function based on the type size. I'm not convinced this is a good idea at this point. As far as I know, it is ok to have the same size for double and long double. However, they are distinct types.
