Brad King 6d74e7870b Ninja: Add dependencies on system-provided header files (#14914)
When system-provided packages are upgraded we must re-compile sources
depending on their headers.  Use `-MD` instead of `-MMD` so that the
generated depfiles do not exclude system headers.

Gregor Jasny 2cae5128fd Apple: Enable -isystem for GNU Compiler >= 4 (#15953)
Due to #4662 -isystem support was disabled for all GNU Compilers
on Apple platforms. But the change was probably a just work around
for a broken compiler on Tiger (see 10837#c27206). So we tighten
the condition to only kick in for GCC versions earlier than 4.
That should ensure sane behavior for Xcode 3.2 and later.

Juhani Simola 99a9c7e51a IAR: Add support for using this compiler with the Ninja generator
The dependency flags require recent versions of `iccarm` and `iccavr`.
The multi-rule dependency generated with `--dependencies=m` does not
work well with Ninja, so use `--dependencies=ns` instead.

Chuck Atkins 928d2085d8 CrayPrgEnv: Don't use absolute paths for imlicit libraries
When parsing implicit include dirs, link dirs, and link libs, all
arguments are resolved to absolute paths instead of relative paths.
This is correct for link and include directories but link libraries
should only include the library name, not it's path.

Chuck Atkins a7ef02253b Cray: Refactor the Cray platform files to use compiler wrapper checks
This is an extensive refactoring of the Cray compiler wrapper usage.
Using the new compiler wrapper checks, the CrayPrgEnv info files have
been moved from Platform/ to Compiler/.  The adjusted naming convention
allows the compiler-wrapper information files to be loaded for both the
CrayLinuxEnvironment platform when cross-compiling and the Linux
platform if building natively on the Cray compute nodes.  It also
creates a separation of common arguments for compiler id and language
information used to perform the appropriate introspection of implicit
arguments and libraries used by the compiler wrappers based on the
loaded module environment.

James Johnston 7a3277276e Embarcadero: Fix erroneous interpretation of __CODEGEARC_VERSION__.
As per the following link:

  http://docwiki.embarcadero.com/RADStudio/Seattle/en/Example_of_CODEGEARC_VERSION_Macro

The major/minor versions must be decoded as a hex string, while the patch
version must be decoded as a normal decimal string.

As an example, C++ Builder XE 8.1's bcc32.exe sets this macro to 0x070189C9.
The file version of bcc32.exe is 7.1.5570.35273.  Therefore, the correct
interpretation to COMPILER_VERSION would be 7.1.35273.

Brad King 441dba8032 Project: Guess default standard dialect if compiler was forced (#15852)
Prior to commit v3.4.0-rc1~71^2 (Project: Determine default language
dialect for the compiler, 2015-09-15) we always guessed the default
language standard dialect based on the compiler version.  This was not
reliable so that commit switched to computing the default language
standard dialect while detecting the compiler id.

When a toolchain file uses CMakeForceCompiler to set the compiler id
then the detection does not occur.  Therefore commit v3.4.0-rc1~54^2
(Project: Don't require computed default dialect if compiler was forced,
2015-09-22) made the lack of detection an error only if the compiler was
not forced.  However, this means that projects using CMakeForceCompiler
no longer even get the guess that we had before so <LANG>_COMPILER does
not work.

Due to the sophistication of CMake's compiler detection logic projects
should be ported away from using CMakeForceCompiler.  In the meantime,
restore a guess of the default language standard dialect when the
compiler is forced.

Stephen Kelly d13758514c Project: Don't require computed default dialect if compiler was forced.
Commit 7235334a (Project: Determine default language dialect for the
compiler., 2015-09-15) introduced a mechanism to determine the default
dialect used for the running compiler.  If conditions in
the <CompilerId>-<Lang>.cmake file are such that compile features for
that version of the compiler should be supported, the _DEFAULT_STANDARD
is set to the computed value.

However, the CMakeForceCompiler module allows users to bypass execution of the
compiler by CMake.  In that case, do not set the _DEFAULT_STANDARD variable at
all, which effectively disables the compile-features where the module is used.

No compile features have ever been recorded where the module is used so no
functionality is lost.

Green Hills MULTI is an IDE for embedded real-time systems.  The IDE's
product page can be found here:

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.
