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.

Define an empty string in CMAKE_<LANG>_STANDARD_DEFAULT to mean that
the toolchain has no notion of lanuage standard levels. In this case
the <LANG>_STANDARD[_REQUIRED] properties will have no effect.
Update the RunCMake.CompileFeatures test to exclude the
LinkImplementationFeatureCycle test when there is no standard default.
It can never fail because no use of specific features will adjust the
CXX_STANDARD level required for any target since the standard levels
have no meaning in this case.
ab9fa54d Xcode: Switch to internal CMAKE_MAKE_PROGRAM lookup by generator (#15324)
11e2e6ca Xcode: Select make program at build time
e4055a61 Xcode: Add internal API to find xcodebuild
The "cmakexbuild" wrapper is not needed for Xcode 4 and above, and the
path to it may change when CMake moves. Avoid storing a specific path
to a build program in CMakeCache.txt and instead compute the value for
CMAKE_MAKE_PROGRAM on demand. However, if a user does set the value
explicitly then honor it.
This does for Xcode what commit v3.0.0-rc1~260^2~4 (VS: Switch to
internal CMAKE_MAKE_PROGRAM lookup by generators, 2013-11-15) did for
Visual Studio generators.
Custom command path normalization added in commit v3.1.0-rc1~471^2
(add_custom_command: Normalize OUTPUT and DEPENDS paths, 2014-05-28)
broke use of OBJECT_DEPENDS to bring in custom commands because the
latter paths were not normalized too. Normalize them and add a test
case.

With the Makefile generators we expect that touching or modifying the
input file of a configure_file, or removing its output, will cause CMake
to re-run on the next build. Extend the RunCMake.configure_file test
with a case covering this. Also check that CMake does not re-run if
nothing has changed.
With the Makefile and Ninja generators we expect that touching the input
source file for a try_compile will cause CMake to re-run on the next
build. Extend the RunCMake.try_compile test with a case covering this.
Also check that CMake does not re-run if nothing has changed.
Whenever feature support is added to a compiler, the CompileFeatures
test needs to be updated to set expected availability of features.
Add #error directives to ensure the test fails if expectations are
not set.

Read file names from the lines of a specified file. Reject input lines
starting in '-' to leave room for option parsing to be added later. Add
just '--add-file=' now to allow files starting in '-' to be specified.

Most functionality is already implemented in Source/cmCoreTryCompile.{h,cxx}.
Document and improve argument parsing.
This functionality is already being used by a number of modules, like
CheckCSourceCompiles.cmake, but it is not documented.
Shorten the add_definitions command test directory and target names to
avoid creating really long paths that fail with some tools on Windows.
While at it, remove unnecessary project() command calls.

When curl is given a URL of the form '<something>://' it tries to
resolve '<something>' as a host name. If the host happens to exist and
have a server then the drop might actually appear to work. Instead use
an explicit '-no-site-' host to ensure it cannot connect.

Fix the <lang>_non_features try_compile calls to work correctly when
there is a space in the path. Otherwise they all fail due to the space
instead of the lack of a feature.
