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),
c_variadic_macros (C99) and c_static_assert (C11). This feature
set can be extended later.

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

f5bf9d4311 Tests: Make CompileFeature tests use highest standard known. 
Remove the use of check_cxx_source_compiles which is now just getting in
the way.

Blacklist the cxx_alignof feature in the test with GNU 4.7. The test
file compiles, but it is documented as available first in GNU 4.8.

f782417b8c Features: Record the oldest supported compiler. 
This may be used to ensure that features are reported correctly
only if the compiler minimum version is met.

Stephen Kelly
9d285600d4 Project: Generate the CXX compiler Id test from multiple files. 
This will allow sharing of the logic of the order to test compilers in
and the preprocessor macros used to do that and to determine the
version components.

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.

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.
