When a function takes a variable number of pointer arguments, with a zero
...
pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

Final Changes For PR495:
...
This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:
makeReadable -> makeReadableOnDisk
makeWriteable -> makeWriteableOnDisk
makeExecutable -> makeExecutableOnDisk
setStatusInfo -> setStatusInfoOnDisk
createDirectory -> createDirectoryOnDisk
createFile -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy -> eraseFromDisk
rename -> renamePathOnDisk
These changes pass the Linux Deja Gnu tests.

For PR495:
...
Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:
appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set
Changes pass Dejagnu and llvm-test/SingleSource tests.
