instead use the FPU to convert subnormals to normals. (NB: Further
simplification is possible, such as using the FPU for the rounding
step.)
This fixes a bug reported by stefanf where long double subnormals in
the Intel 80-bit format would be output with one fewer digit than
necessary when the default precision was used.
for libarchive error messages. Mostly, this
avoids a portability headache related to
copying va_list arguments (some FreeBSD 5
platforms require va_copy; FreeBSD 4 doesn't
support va_copy at all). It also dramatically reduces the
size of libarchive for embedded applications:
a minimal "untar" program using libarchive can now be
under 64k statically linked (as opposed to ~100k
using library *printf() functions).

* Reference-count the directory data so that
we don't leak memory.
* Correctly step through the directory records
(skipping unrecognized extensions)
* Use better defaults for file modes
* Sort directory entries by offset of the end of the file
rather than the beginning of the file. This fixes a
lot of "out-of-order" problems with zero-length files,
in particular.
* Style fixes, remove some debug code, add some error messages.
This seems to be able to extract a TOC and extract files from
the couple of ISO images I've tested it with.
Treat this as experimental proof-of-concept code for the
moment. There are still a bunch of debug messages (there
are a few oddities in ISO9660 that I haven't yet figured
out how to handle), a lot of bugs to be addressed (this
code leaks memory very badly), and a lot of missing features (no
Rockridge support, in particular). I'd appreciate
feedback from anyone who understands ISO9660 format
better than I do. ;-)

a too-long name that overflowed the ustar fields and triggered

this allows GNU tar to correctly extract such entries even

Simplify signal code because of above (by David Xu).
Use macros for libpthread usage of pthread_cleanup_push() and
pthread_cleanup_pop(). This removes some instances of malloc()
and free() from the semaphore and pthread_once() implementations.
When single threaded and forking(), make sure that the current

Use private mutexes for libc and libpthread. Signals are
deferred while threads hold private mutexes. This fix also

Fix race condition in condition variables where handling a
