Like on OS X and Linux, ICC uses the native compiler's standard library
headers, so the C++11 features that depend on headers need special
attention.
* <initializer_list> is missing with MSVC 2012. It is present on 2010
for some reason and it appears to work
* ICC disables Unicode string support prior to MSVC 2015, probably
because MSVC Standard Library headers have a typedef for char16_t
std::nullptr and std::move should have come with MSVC 2010, but I'm not
keeping compatibility with MSVC 2008. It's been deprecated since ICC
14.0 (Composer XE 2013 SP1, released in 2013) and support was removed in

Expand Linux distribution detection to /etc/redhat-release and
/etc/debian_version to follow what /usr/bin/lsb_release script does.
If /usr/bin/lsb_release fails to extract the distribution information
from /etc/lsb-release, it then checks /etc/redhat-release and, as a last
fallback, /etc/debian_version.
Some Red Hat distributions have a /etc/lsb-release file that
does not provide the values we are looking for (DISTRIB_ID,
DISTRIB_RELEASE and DISTRIB_DESCRIPTION).
If both productType or productVersion are empty after reading
/etc/lsb-release, readEtcLsbRelease() will return false, allowing
further parsing of /etc/redhat-release. This scenario mimics what
the /usr/bin/lsb_release script does if /etc/lsb-release does not
contains enough information.
The productType and productVersion returned by QSysInfo after reading
/etc/redhat-release match the distributor id and release information
returned by the /usr/bin/lsb_release script.
For Debian Linux distributions where /etc/os-release, /etc/lsb-release
and /etc/redhat-release are not available nor usable, the
/usr/bin/lsb_release script also checks for the /etc/debian_version
file.
In this case, we also enable parsing of /etc/debian_version to retrieve a
fallback productVersion, the productType being set to Debian.

typically excludes status/menu bars and application launchers.
On some platforms it may still be possible to place windows in the areas
of the screen that are outside of the available geometry, but this will
result in the window being partially covered by (possibly) transparent
system UIs. The new flag allows the user to specify that when maximizing
the window it should try to cover as much as possible of the screen
geometry (in contrast to going full screen, which would typically
hide any system UIs).
For iOS this is a common use-case, as the status bar is transparent,
and the user-interface guidelines for iOS7 and up recommend taking
advantage of the full screen space, while keeping any user-interaction
elements still inside the available geometry of the screen.
