I don't think that will work on any standard C++ compiler.

Given:

typedef xxx u_int32_t;
namespace resip { typedef xxx u_int32_t; }
using namespace resip;

Then "::u_int32_t" is ambiguous - your using directive made the resip one
visible in the global namespace, so there's no way to tell which of the two
you mean.

All you can do (assuming the Berkley DB one can't be moved into a namespace)
is to delete the "using namespace resip;" and replace it with either
explicit resip:: qualifications everywhere, or a sprinkling of "using
resip::foo;" declarations. (Where foo != u_int32_t.)

(Use of using directives is best avoided in general for this sort of
reason.)
