The reference is in this function:
_ZNSbIhSt11char_traitsIhESaIhEE4_Rep9_S_createEmRKS1_
I think this reference comes from line 143 in include/bits/basic_string.tcc.

No, all char's are not unsigned on HPUX.  I think this probably has
something to do with instantiation on systems without weak support.
Don't these systems require explicit instantiation?
