Stephen Kelly d0af0faefb WCDH: Make the header -Wundef safe for the C language.
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.

Stephen Kelly a3d0ae1758 Features: Fix the default C dialect for Clang and GNU.
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.

Stephen Kelly ded30405b2 Features: Don't record for AppleClang
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.

3151024d QNX: Add missing flags for configurations and artifact creation.

Stephen Kelly 3151024d24 QNX: Add missing flags for configurations and artifact creation.
Commit v3.0.0-rc1~111^2 (QNX: Introduce QCC compiler id for that
QNX platform compiler., 2014-01-20) split handling of the QNX QCC
compiler into a separate compiler-id.  That refactoring results in
the QCC compiler not using the CMake-compiler-id "GNU", which means
that the __compiler_gnu macro is no longer executed for it.

Add Compiler/QCC*.cmake modules to define and call the __compiler_qcc
macro and teach it to call __compiler_gnu internally.  Remove the
corresponding pieces from the Platform/QNX*.cmake modules.

It is also necessary to change the language conditional to dereference
the lang macro parameter, which is another bug introduced by the
same commit.  The extra -lang-c++ flag is only necessary when the CXX
compiler is specified as 'qcc' instead of 'QCC' in the toolchain file,
which is why this bug was not noticed before.  The flag is also necessary
in that case when linking in order to find the appropriate standard
libraries.  The flag was not previously added when linking executables,
so linking failed even with CMake 2.8.12 with the lower-case compiler-id.

Stephen Kelly e0890d03a4 Features: Extend concept to C language.
Add properties and variables corresponding to CXX equivalents.

Add features for c_function_prototypes (C90), c_restrict (C99),

set can be extended later.

Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader
to conditionally represent the c_restrict feature.

Stephen Kelly 1df2116bfa Features: Decay language flag if requested is not available.
Use the highest standard compile flags available if requested language
version is too new.

This supports use-cases like

 set(CMAKE_CXX_STANDARD 14)

 # Compiled with -std=c++11 with GNU 4.7, which has no -std=c++14
 # or equivalent flag
 add_executable(main main.cpp)

This can be used in combination with preprocessor defines which
communicate the availability of certain language features for
optional use.

Rolf Eike Beer b0f277db38 HP aCC: record compiler flag for Ansi C++98 support for version 3.80 onwards
Old versions of aCC need a special compiler flag to get full C++98 template
support as e.g. CMake itself or the Complex and ComplexOneConfig tests need.
The same versions need a special flag to get a proper C++ library, too.
