There is, but it's not relevant. The problem apparently is that while Sun 
5.9 (and possibly 5.8 as well) can handle the "conforming" unspecified bool, 
it does incorrectly compile 'delete sp' because of the conversion since it 
can 'delete' a pointer to member for some reason. There is a 1.34 workaround 
in place for Sun 5.8 and below that makes it use "operator bool" instead, 
but it leads to another failure, shared_ptr_compare_fail.

If you have time to check whether the third "unspecified bool" path that is 
chosen for old versions of Metrowerks and g++ (see shared_ptr.hpp:406) works 
for Sun 5.9 (and maybe 5.8 as well), we'll switch to that.
