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.
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.
The CMAKE_<LANG>_STANDARD_DEFAULT variable indicates whether the
compiler has any notion of standard levels and that CMake knows
about them. If no language standard levels are available, skip
all logic to attempt to add a flag for the level.
Also fail with an internal error if a bad default value is set.
When targeting Windows with a 64-bit architecture, use "$PROGRAMFILES64"
to get the Program Files folder. Use CMAKE_SIZEOF_VOID_P to check for
the architecture size instead of CMAKE_CL_64 because the latter is not
defined for all compilers.

Initialize CMAKE_SHARED_LINKER_FLAGS_RELWITHDEBINFO_INIT from the value
of CMAKE_EXE_LINKER_FLAGS_RELWITHDEBINFO_INIT rather than the one for
the DEBUG configuration. This typo has been present since the logic was
first added in commit 36db45082e (ENH: fix up several problems with new
stuff, 2002-11-11).

The refactoring in commit v3.1.0-rc1~812^2~16 (stringapi: Pass
configuration names as strings, 2014-02-09) broke the code path in
cmLocalGenerator::GenerateInstallRules that intends to pick a default
install configuration for multi-config generators. Fix the logic to
select an empty default configuration only when using a single-config
generator whose CMAKE_BUILD_TYPE is not set.

When loading the list of target support directories, read the file
with UTF-8 encoding since that is what CMake writes into the file.
This allows us to support international characters in the path to
the build tree containing the target support directories.
Add a GCOV_OPTIONS option to allow specification of custom flags. In
ctest_coverage gcov support, if you set CTEST_COVERAGE_EXTRA_FLAGS, they
get put on the command line before the -o. In this case we remove the
-b and replace it with GCOV_OPTIONS. All other arguments remain the
same.
When staging the package installation, if the first file in a directory
happens to be a symbolic link, make sure we create the directory before
trying to create the link.

In commit v3.0.0-rc1~222^2 (Makefile: Allow "gmake target1 target2 -j",
2013-12-18) we added generation of a .NOTPARALLEL rule and told the
generator it is "symbolic" because the file will never be created.
This causes ".PHONY" to be used. However, "clearmake" does not support
parsing of .PHONY specifically for .NOTPARALLEL, so simply drop it.
This should not affect the role of the .NOTPARALLEL rule for GNU make.
The "/showIncludes" flag is only available with MS C and C++ compilers,
and on compilers that "simulate" them (like Intel for Windows). Fix our
logic to choose this type only for MS tools with these languages. All
other cases need to use "deps = gcc" and define DEP_FILE in the build
rule.
