cloneStack() and inherit() functions missing in 0.10.0

[deepak singh-4]

hi,

   log4cxx::NDC::cloneStack() and inherit() functions are missing from 0.10.0.

   Is there any work around for these functions in the 0.10.0.

   I want to inherit the NDC stack of the parent thread to the child thread.

Thanks

Deepak
