The FindXerces module was added in commit v3.1.0-rc1~155^2 (FindXerces:
New module to find Apache Xerces-C++, 2014-08-17). However, there are
two implementations of Xerces, one in C++:
http://xerces.apache.org/xerces-c/
and one in Java:
http://xerces.apache.org/xerces-j/
Rename FindXerces to FindXercesC to clarify that it is about the C++
implementation.
While at it, add the missing CMake 3.1 release note about this module.

Revert the feature added by commit v3.1.0-rc1~420^2~2 (FindOpenGL:
Provide imported targets for GL and GLU, 2014-05-31). Unfortunately it
does not work on Windows because the full path to each library file is
not actually known. The IMPORTED_LOCATION of an imported target must be
a full path, but OPENGL_gl_LIBRARY is just 'opengl32' on Windows because
the actual library file is in some implicit link directory that we may
know know.
More infrastructure will be needed in CMake to allow a name-only
imported library. Until that exists, we will not be able to provide
imported targets in FindOpenGL.
In commit v3.1.0-rc1~640^2~5 (Clean up usage of if(... MATCHES regex)
followed string(REGEX REPLACE regex), 2014-04-06) we accidentally broke
logging of the implicit library detection. Restore use of the
intermediate 'lib' variable so that the log message is constructed
properly.

The __STDC_VERSION__ macro may be defined or not depending on the
implementation dialect of C. Test that it is defined before testing
its value.
The CXX tests do not need such a change because they define __cplusplus
in all dialects.
Clang 3.4 uses C99 by default, and Clang 3.6 uses C11 by default:
http://thread.gmane.org/gmane.comp.compilers.clang.devel/39379
GNU 4.9 uses C90 by default, and GNU 5.0 uses C11 by default:
https://gcc.gnu.org/gcc-5/changes.html
Test that the default compiler settings result in the expected dialect
macros being defined for both C and CXX. Remove the unused main.c
file from the CompileFeatures unit test.
OS X provides a stub 'java' to inform callers that Java is not present.
When checking the 'java -version' output, look for such a message and if
found pretend 'java' was not found.

Features are currently recorded accidentally for all versions of
AppleClang > 3.4 (I have no idea how that relates to upstream
Clang). Presumably that version has the features which are
accidentally recorded, but in the future features will be
recorded initially for only AppleClang >= 5.1, which would
appear as a feature regression.
Commit v3.1.0-rc1~635^2~11 (Don't load Clang-CXX from
AppleClang-CXX., 2013-11-11) ajusted the logic for the CXX
language. Make a similar change for the C language.
The change in commit v3.1.0-rc1~85^2 (ExternalProject: Fix download
retry logic, 2014-09-13) dropped the file(DOWNLOAD) EXPECTED_HASH
argument. This prevents file(DOWNLOAD) from skipping the download if
the output file already exists with the proper hash. Restore this check
with explicit code in the download script.

Since commit v3.1.0-rc1~1^2~1 (Xcode: Fix compiler id detection for iOS
tools, 2014-10-22) our compiler id detection project sets the product
type to 'com.apple.product-type.bundle.unit-test'. This causes the Ld
command line on which we match the path to the compiler to have a
'CompilerIdC.xctest/' component. The commit updated our regex to match
this, but placed it before the extra './' component that Xcode 5.0 and
below produce. Xcode <= 5.0 prints '/./CompilerIdC.xctest/', so switch
the order of the two components in the regex to match it.
Cleanup of Windows-wcl386.cmake in commit v3.1.0-rc1~693^2 (Watcom:
Cleanup Windows-wcl386 configuration, 2014-04-01) also introduced use of
the 'symfile' link option but did not mention it in the commit message.
There is no way to set the symbol file name of a target, so it is better
to revert that change. It is easy to run 'wstrip *' if the symbols need
to be stripped, but it is very difficult to get the right names for the
.sym files to install with debug/rel_with_deb_info configurations.
