+This fixes the GCC build. GCC seems to be stricter with the position of the
+linkage specification, so just swap the terms to prevent an error that looks
+like:

+Subject: [PATCH] media::learning: Make LabelledExample's move assignment
+ operator noexcept
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The GCC build is currently broken with an error like this:
+
+    ../../media/learning/common/labelled_example.cc:20:1: error: function 
‘media::learning::LabelledExample::LabelledExample(media::learning::LabelledExample&&)’
 defaulted on its redeclaration with an exception-specification that differs 
from the implicit exception-specification ‘’
+     LabelledExample::LabelledExample(LabelledExample&& rhs) noexcept = 
default;
+     ^~~~~~~~~~~~~~~
+
+With GCC, having that noexcept marker requires all members to be marked with
+noexcept themselves, and TargetValue was missing some assignment operators
+and noexcept markers.
+
+clang is fine because we pass -fno-exceptions and it disables the same error
+there, while GCC continues to raise it (bug 843143 and its corresponding CL
+have a longer discussion on this issue).

+MIME-Version: 1.0

color_utils::SetDarkestColorForTesting(SkColor)’:
+    ../../ui/gfx/color_utils.cc:434:12: error: ‘sqrtf’ is not a member of ‘std’

+                sqrt
+
+sqrtf() is not formally part of C++14 as far as I can see even though libc++
+has it in <cmath>. Additionally, we're only dealing with floats in all parts
+of the expression above, so using the float sqrt() overload should be
+harmless anyway.

+Subject: [PATCH] CastActivityManager: Do not make DoLaunchSessionParams' move
+ constructor noexcept
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This fixes the GCC build:
+
+    
../../chrome/browser/media/router/providers/cast/cast_activity_manager.cc:806:1:
 error: function 
‘media_router::CastActivityManager::DoLaunchSessionParams::DoLaunchSessionParams(media_router::CastActivityManager::DoLaunchSessionParams&&)’
 defaulted on its redeclaration with an exception-specification that differs 
from the implicit exception-specification ‘’
+     CastActivityManager::DoLaunchSessionParams::DoLaunchSessionParams(
+     ^~~~~~~~~~~~~~~~~~~
+
+With GCC, having that noexcept marker requires all members to be marked with
+noexcept themselves, and MediaRoute, CastMediaSource and url::Origin need
+the right annotations. Just making DoLaunchSessionParams not noexcept is the
+least intrusive solution for now.
+
+clang is fine because we pass -fno-exceptions and it disables the same error
+there, while GCC continues to raise it (bug 843143 and its corresponding CL
+have a longer discussion on this issue).
+
+Bug: 819294
