Don't even try to compare gets with auto_ptr... One is HUGE security hole
and another one some stuff that should be used carefully, it isn't more
dangerous that strncpy and far less dangerous that sprintf that goes

When C++11 was released and how well it is supported by now?

Ok when I started for example Boost.Locale few years ago No major widely
available compiler had provided unique_ptr.

I'm using Ubuntu LTS 14.4 (a distro one year old with long support) and gcc-4.8
does not support regular expressions yet!

At another place I'm using up-to-date RHEL 6.x... it comes with gcc-4.4 and guess
what is C++11 support level is there?

And yet no-major compiler (besides MSVC 2015 or something like) really support
C++11 char16_t/char32_t (I mean all stuff including facets)

There is HUGE difference between the standard release time and what world
actually uses... MSVC does not even support properly C99 yet and it was released
more than a decade ago and it is C much simpler language.

So it would take a very long time until industry will move to C++11 and
until all major main-stream compilers would have decent C++11 support.

So removing very useful stuff that isn't really that bad and that is
used in library interfaces (so its removal breaks APIs) it what is
what Linus Torvalds would say "brain damaged" decision.
