bzip2 with autotools
====================

Switching bzip2 to autotools 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>, or
Federico Mena Quintero <federico@gnome.org>.

Autotools version binaries are exactly equal to
bzip2-1.0.6.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.

Shared library exports only public symbols.

To be super-safe, I incremented minor number of the library file, so
both instances of the shared library can live together.
