Follow up change from commit ffa6faa4 (libarchive: Include cm_zlib.h to
get zlib used by CMake, 2011-12-20) for new includes of zlib.h in
updated libarchive.
The archive_string_conv type sc variable already freed via free(sc) on
the other hand in second line we are tyring to free its subset via
free(sc->from_charset) this will cause a problem because we couldn't
reach sc after first release.

caught by clang's -fsanitize=shift. A small unsigned int was
promoted, according to C's regular promotion rules, to a signed
int, it was then left shifted. This sometimes pushed a 1 into
the sign bit, which is undefined behaviour. Fixed by using
unsigned temporaries.
The CMake TarTest fails with the error
mbsnrtowcs.c:116: __mbsnrtowcs: Assertion
`status == GCONV_OK || status != GCONV_EMPTY_INPUT ||
status == GCONV_ILLEGAL_INPUT || status == GCONV_INCOMPLETE_INPUT ||
status == GCONV_FULL_OUTPUT' failed.
on very old glibc versions. Work around the problem by pretending that
mbsnrtowcs does not exist. Libarchive will fall back to mbrtowc.
Use the approach originally used in commit f91b3c1d (Add options to
build with system utility libraries, 2006-10-19) for all other
third-party libraries. Create a "cm_bzlib.h" header wrapper that
robustly includes the header from the bzip2 library chosen for the CMake
build (either builtin or system version). Include the header wrapper
anywhere we need the API provided by <bzlib.h>.
We cannot suppress PGI compiler warnings completely because even with
the "-w" flag the compiler still writes a message containing "compilation
completed with warnings" to stderr.
A warning is triggered by expressions like
test ? NULL : ptr_to_const_char
test ? ".." : ptr_to_const_char
that the PGI compiler handles incorrectly. It chooses the pointer type
of the first option (either void* or char*) and warns about conversion
of the second without a cast. Flip the expression logic to
!test ? ptr_to_const_char : NULL
!test ? ptr_to_const_char : ".."
to help the compiler choose the proper result type.
Configure the result as definition HAVE_STRUCT_STATVFS_F_IOSIZE and use
the member only if it exists. At least one platform (IRIX) provides
struct statvfs without this member.
VS 6 warns verbosely when WINVER >= 0x0500. Avoid defining WINVER and
_WIN32_WINNT to higher than 0x0400 on VS 6. Provide missing API
declarations in archive_windows.h when we do not get them from
<windows.h>. Provide GetVolumePathNameW because VS 6 does not declare
it regardless of the API version.
At least one compiler (Borland) defines mode_t as just "short" which is
signed. This breaks code like
switch(archive_entry_filetype(e)) {
case AE_IFREG:
...
}
if AE_IFREG and other constants have a longer signed type (int) because
sign extension of the mode_t return type from archive_entry_filetype
changes its value. Avoid the problem by ensuring the type of the
constants matches mode_t.
This change was originally made in commit a73acfbe (Fix for mode_t with
signed types, 2009-11-07). Port it to the new libarchive snapshot.
Mangle the open_FILE symbols to avoid conflict with open_file:
Warning: public '_archive_read_open_file'
in module 'archive_read_open_filename.c' clashes with
prior module 'archive_read_open_file.c'
Warning: public '_archive_write_open_file'
in module 'archive_write_open_filename.c' clashes with
prior module 'archive_write_open_file.c'
This workaround should not go upstream because it will break when
mixing compilers.
Restore Windows 64-bit lseek removed by upstream svn revision 3826
(Cast away __la_lseek(), use _lseeki64() instead, 2011-11-21). We
need it on Borland.
Make changes equivalent to those originally made by commits
bd56626a (Fixes for the OSF operating system build, 2010-09-08)
92c082b1 (Add a fix for the inline keyword on the osf os, 2010-09-10)
but based on the updated libarchive snapshot.
Remove add_subdirectory() calls for directories not included in the
reduced libarchive snapshot. Remove options that configure settings in
the missing directories.
This version of MinGW defines _SSIZE_T_ for ssize_t. This patch is
based on upstream libarchive SVN commit 3649 (Fix build with mingwrt
3.20, 2011-08-27).

If neither MAJOR_IN_MKDEV or MAJOR_IN_SYSMACROS is defined then provide
our own implementation of these macros locally. This complements the
change in commit cf5ad183 (Fix major() check for LSB 4.0, 2011-01-12).
This patch is based on upstream libarchive SVN commit 1553 (Shuffle the
major/minor/makedev support a bit; this should work on both Windows and
Haiku, 2009-10-31).

Dereferencing a 0-pointer is undefined behavior, not a deterministic
crash. Use a 1-pointer instead. This also avoids a warning by Clang
about the undefined behavior.
At least one version of GNU tar (1.15.1 with Fedora patches) does not
recognize these attributes and exits with error. Do not generate them.
Patch from upstream libarchive svn r2563.
