* Disabled shared-library building, as some API breakage is still likely. (I didn't realize it was turned on by default.) If you have an existing /usr/lib/libarchive.so.2, I recommend deleting it. * Pax interchange format now correctly stores and reads UTF8 for extended attributes. In particular, pax format can portably handle arbitrarily long pathnames containing arbitrary characters. * Library compiles cleanly at -O2, -O3, and WARNS=6 on all FreeBSD-CURRENT platforms. * Minor portability improvements inspired by Juergen Lock and Greg Lewis. (Less reliance on stdint.h, isolating of various portability-challenged constructs.) * archive_entry transparently converts multi-byte <-> wide character strings, allowing clients and format handlers to deal with either one, as appropriate. * Support for reading 'L' and 'K' entries in standard tar archives for star compatibility. * Recognize (but don't yet handle) ACL entries from Solaris tar. * Pushed format-specific data for format readers down into format-specific storage and out of library-global storage. This should make it easier to maintain individual formats without mucking with the core library management. * Documentation updates to track the above changes. * Updates to tar.5 to correct a few mistakes and add some additional information about GNU tar and Solaris tar formats. Notes: * The basic 'tar' reader is getting more general; there's not much point in keeping the 'gnutar' reader separate. Merging the two would lose a bunch of duplicate code. * The libc ACL support is looking increasingly inadequate for my needs here. I might need to assemble some fairly significant code for parsing and building ACLs. <sigh>
