bzip2/bzip2-1.0.6-autoconfiscated.patch
Cristian Rodríguez e8b7e041b9 Accepting request 99345 from home:elvigia:branches:Archiving 
- bzlib: open file descriptors with O_CLOEXEC, but just like 
 the zlib case, only when bzopen() is used and not bzdopen()
 to avoid messing up with the caller's semantics.
 It is responsability of to initiator to set that flag in such case.
- Replace error prone list of exported symbols with proper use of
  GCC visibility features.

+bzip2 autoconfiscated
+=====================
+
+Temporarily at http://ftp.suse.com/pub/people/sbrabec/bzip2/ expecting
+that it will become a new upstream version to prevent per-distribution
+shared library patching done by nearly each Linux vendor separately.
+
+Autoconfiscation brings standard ./configure ; make ; make install
+installation, seamless support of DESTDIR, automatic check for supported
+CFLAGS, standard shared library support, automatic large files CFLAGS
+check and all things that are supported by automake.
+
+It makes obsolete Makefile-libbz2_so and README.COMPILATION.PROBLEMS.
+Now configure should automatically detect correct build flags.
+
+In case of any problem or question with autotools support feel free to
+contact me: Stanislav Brabec <sbrabec@suse.cz>
+
+Autoconfiscated version binaries are exactly equal to
+bzip2-1.0.5.tar.gz. There are only few changes. See below.
+
+
+New features:
+
+Trivial link man pages for bzcat and bunzip2 added.
+
+bzip2.pc file for pkg-config. Packages can use it for checks.
+
+
+Incompatible changes:
+
+soname change. Libtool has no support for two parts soname suffix (e. g.
+libbz2.so.1.0). It must be a single number (e. g. libbz2.so.1). That is
+why soname must change. But I see not a big problem with it. Several
+distributions already use the new number instead of the non-standard
+number from Makefile-libbz2_so.
+
+To be super-safe, I incremented minor number of the library file, so
+both instances of the shared library can live together.
