libbind library question

[Gopal Kulkarni]

I am trying to link the ported Windows DNS resolver library (libbind) into
my application. I have resolved all the linking issues, except for the
_h_errno variable. I get an unresolved external linkage error.  I am using
the h_errno (NOT _h_errno) variable in my application.  I could never find
the _h_errno variable defined anywhere. I exported both _h_errno and
h_errno variables from the resolver library dll and that did not help. 

Any ideas?
