operator= is a private member of AString

Trying to compile last relaease (R3) with gcc on Linux I stumbled on error in `UI/Common/Update.cpp':

Similarily with clang:

They didn't seem to be Linux specific so I report them.
Ed. After later examination it seems to be somewhat Linux related as mingw-gcc, also v8, does manage to compile that, with some warnings regarding fallthrough in lines 64, 74.

There were other, like min/max undefined and isblank() undefined but I managed them. The first, on a list did not. And there is a question here, as it complains about lack of `isblank' which stems from lack of <wchar.h>, <wctype.h>. Shall I add <ctype.h> or <wctype.h> as it's available in include?

C++ is not my forte.

All errors are attached to the post.

I have no idea on that also ... How does Igor get it's linux binaries build?
Maybe you can ask him?

It's 7-Zip-zstd specific, so I ask here.

In the diff attached line 900 is marked with `///', within section between L884-L914 that is added.
