Hi Peter, All,

Regarding the first code snippet (quoted below), I'd
guess that the precompiler doesn't cast for const alone
(to cast a parameter from char* to const char*), and the
real problem is the incomplete (ahem) const correctness of
the isc_* API. I would assume that the signature of
isc_transact_request should have some number of "const"
inserted.

Regards,
Peter Jacobi
