Nit: Do we need this block or will the if (!nss3_dll_) work for us?  I guess
having the NOTIMPLEMENTED() is useful.

[kuchhal, 2009/06/09 00:18:31]

Yes returning empty string will work too but may be since we are not testing
this on MAC we want to make it clear that only Win & Linux are supported so far.
