Stephen Kelly 7235334a2f Project: Determine default language dialect for the compiler.
Use the __cplusplus and __STDC_VERSION__ macros to automatically
determine the default dialect for the compiler while determining its
id and version.

Brad King c736de7b28 Factor an <INCLUDES> placeholder out of <FLAGS> in rule variables
Teach the Makefile and Ninja generators to substitute for an <INCLUDES>
placeholder instead of putting -I in <FLAGS>.  Update our values for

  CMAKE_<LANG>_COMPILE_OBJECT,
  CMAKE_<LANG>_CREATE_ASSEMBLY_SOURCE, and
  CMAKE_<LANG>_CREATE_PREPROCESSED_SOURCE

to place <INCLUDES> just before <FLAGS>.

Brad King 228643af6d AppleClang: Use modern C++14 standard flags for Apple Clang 6.1
The Apple Clang 6.1 compiler that comes with Xcode 6.3 is aware of the
modern -std=c++14 and -std=gnu++14 flags, so use them instead of the
"1y" flags.

Brad King a33fb493de XL: Drop -qalias=noansi from default C flags
This was added without explanation by commit v2.8.2~1138 (Add initial XL
C compiler flags for safer builds, 2009-09-30).  It is not consistent
with our default C++ flags for XL and disables several optimizations, so
drop it from our default flags for C.

Brad King 7cd539b163 Add support for Concurrent Fortran 77 Compiler
The Concurrent Fortran compiler (ccur.com) is available on Linux and can
be used much like the GNU Fortran compiler.  Currently it has no
preprocessor symbols to identify it so we need to detect it by matching
compiler output.

Geoff Viola 48004d9dbe Add a 'Green Hills MULTI' generator on Windows
Green Hills MULTI is an IDE for embedded real-time systems.  The IDE's
product page can be found here:

 http://www.ghs.com/products/MULTI_IDE.html

It supports cross compiling on ARM, Intel x86, and other architectures
with various operating systems.  The IDE exists on Linux and Windows
host systems, but CMake will currently only generate the project files
on Windows host systems.

Brad King ecb1d5b47a Features: VS 2013 Update 3 supports initializer lists (#15494)
VS 2013 originally claimed to support initializer lists but a bug was
found in which it generated bad code silently.  For this reason we
previously considered support to not be present.  However, Update 3 adds
a hard error on cases that previously generated bad code, so it is now
safe to use initializer lists with VS 2013 Update 3 or greater.  At
worst a compiler error will be issued in the cases that do not work, but
that is no different from any other compiler-specific workaround a
project code may need.

Stephen Kelly fb3487a997 Features: Fix C90 feature detection.
This bug caused c_function_prototypes to not be recorded at configure
time when compiling with -std=gnu99 or similar. In the case of feature
recording, that was not a problem, because the logic in
CMakeDetermineCompileFeatures.cmake currently assumes that a feature
present for an earlier standard is present for a later standard.

However, the detection strings are also used in WriteCompilerDetectionHeader,
so the feature macro has been defined to '0' when using a later language
dialect.

Fix that by not checking the existence of the __STDC_VERSION__ macro at
all when detecting C90 features.

Stephen Kelly 9d767810e1 Features: Populate CMAKE_<LANG>_STANDARD_DEFAULT only for supported compilers.
If no compiler feature information is known for a given compiler
version, do not set a language standard default either.  The two
settings must be recorded consistently.

Stephen Kelly bfc995cc3b Features: Remove wrong content from else() condition.
As this is not elseif(), the content has no effect.

Rather than changing it to an elseif(), remove the conditional content.
All versions of GNU prior to 5.0 default to C90/89.

Clang-C.cmake has a similar code block which correctly uses
elseif() for setting the default C dialect to C99.  That may have
been updated from a C90 default at some point, so leave the
version condition there in place for now.

Stephen Kelly a60027a642 Features: Ensure appropriate return value from feature test macros.
GNU-CXX already has complex logic and sets the _result to 0 before

Brad King be1109d811 Oracle/Sun: Fix Fortran preprocessor rule generation
The SunPro Fortran compiler uses "-F" instead of "-E" to request
preprocessing.  The output does not go to stdout so use "-o" to

assembly and preprocessed targets for Fortran, 2014-11-05).
