ENH: make CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS the default and remove the property.  If any value is specified in an endif, endforeach, endwhile, etc then make sure it matches the start string.  If no values are given then it is no longer an error.

  - Add support to get RPATH and RUNPATH entries.
  - Add support to get file offsets to strings.
  - Add more DT_* tags to byte swapping.

BUG: cmComputeLinkInformation::CheckImplicitDirItem needs to extract the filename portion of the link item to test against the library regex.

  - Use a response file when enabled by
    CMAKE_<LANG>_USE_RESPONSE_FILE_FOR_OBJECTS
  - Enable for C and CXX with cl (MSVC)
  - Enable for Fortran with ifort (Intel Fortran)

  - Enabled when system provides elf.h
  - Introduce cmELF class to parse ELF files
  - Use in cmSystemTools::GuessLibrarySOName to really get soname

BUG: Apply patch from bug#6445.  Add preprocessor definitions to assembly and preprocessing build rules.

ENH: Add support to C compiler identification for void return type from main.  Cross-compilers for embedded platforms may require it.

ENH:  Adjust when log is cleared.  Its kept doing generate,
      and cleared when changing the source directory.
      #6358.

apparently rpmbuild can't handle paths with spaces and can't handle
variables in comments...

  - Write a single source file into the compiler id directory
  - This avoid requiring the compiler to behave correctly with
    respect to include rules and the current working directory
  - Helps to identify cross-compiling toolchains with unusual
    default behavior

ENH: Simplify make build rule generation by removing use of OBJECTS_QUOTED and TARGET_QUOTED rule variables and updating the generation of OBJECTS to always use the newer cmLocalGenerator::Convert method.

  - Its <iosfwd> header includes windows.h which
    defines GetCurrentDirectory
  - It defines 'interface' so we cannot use it as
    a variable name.

  - Reduce false positives in cases of unknown soname
  - Make library extension regular expressions match only at end of string
  - When linking to libraries in implicit dirs convert to the -l option
    only if the file name is one that can be found by the linker
    (ex. /usr/lib/libfoo.so.1 should be linked by full path)
  - Add cmSystemTools::GuessLibrarySOName to guess the soname of a
    library based on presence of a symlink
  - In cmComputeLinkInformation try to guess an soname before assuming
    that a third-party library is built without an soname
  - In cmOrderDirectories guess the soname of shared libraries in cases
    it is otherwise unknown

  - Use linker search path -L.. -lfoo for lib w/out soname
    when platform sets CMAKE_PLATFORM_USES_PATH_WHEN_NO_SONAME
  - Rename cmOrderRuntimeDirectories to cmOrderDirectories
    and generalize it for both soname constraints and link
    library constraints
  - Use cmOrderDirectories to order -L directories based
    on all needed constraints
  - Avoid processing implicit link directories
  - For CMAKE_OLD_LINK_PATHS add constraints from libs
    producing them to produce old ordering

BUG: Link scripts should be generated with copy-if-different and included as a dependency of the link rule.

  - Reference export() and install(EXPORT)
  - Fix to support OUTPUT_NAME in simple cases
