Log Message:
Changes 5.6.22:
* Noisy compiler warnings on FreeBSD 10 were silenced.
* CMake workarounds for older Mac OS X and XCode versions were removed. On Mac \ 
OS X, compilation always uses Clang, even for 32-bit builds.
* Previously, the MYSQL_MAINTAINER_MODE CMake option was turned on by default \ 
for debug builds and off for release builds, and MYSQL_MAINTAINER_MODE caused \ 
-Werror to be enabled when building with GCC. This made it cumbersome to enable \ 
-Werror under certain conditions, such as when compiling with Clang.
* Build support was modified to produce the same warnings for Clang as for gcc.
* CMake configuration for the Clang compiler sets more appropriate flags for \ 
building on Linux. Specifically, -g -fno-omit-frame-pointer -fno-strict-aliasing \ 
is now added.
* Bugs fixed.
