[pdal] build errors on head (win32)

[Michael P. Gerlek]

The OCI stuff isn't building under win32 right now, for two reasons:

* Cloud:: Cloud() and Cloud::~ Cloud() are declared and used, but not defined

* the new "bind" code totally fails to compile under win32 with boost 1.46.1 (lines 67 and 71 in oci Reader.cpp, and two more in the Writer), see below

I've locally commented out those 4 bind lines and stubbed in empty definitions for Cloud() and ~Cloud(), and everything builds and passes okay.
