Add a patch sent by Tim Burris <[email protected]> adding private operator=
declarations to class declarations that do not support copying (for
instance because of const members). Apparently at /W4 Visual C++ warns
unless this is the case, and it seems reasonably good practice to
disable copying on most of these objects anyway due to pointer and
reference aliasing.
Instead of adding an operator= to User_Interface, I made the member
preset_passphrase non-const. This seemed like a cleaner solution to me.
(It may also be the cleaner solution in the pubkey code)
