This distribution was built using an alternate build system. The original
distribution used a simple Makefile, which had to be heavily customized to
meet the needs of modern cygwin and MinGW systems.  Furthermore, it was
wholly unsuited for building the distribution in a cross-hosted environment.

Keith Marshall <keithmarshall@users.sf.net> implemented an autoconf-based
build system, to facilitate cross-hosted building for use with MinGW.  This
build system consists of the following original files:
	configure.ac
	Makefile.in
	aclocal.m4
	libbz2.def.in
found in the 'cygming-autotools-buildfiles.tar.gz' tarball included within
the bzip2-$VER-$REL-mingw-src tarball.

The source preparation phase of the build runs autoconf, which creates the
following file(s):
	configure
In addition, the source preparation phase explicitly removes the original
Makefile from the $srcdir, as a new Makefile will be generated in the
$builddir by the configure phase of the build.

This configure script is NOT distributed in this package; it is assumed that
the 'autoconf' tool is available.  The proper (non-automated) procedure is:

	unpack bzip2-$VER-$REL-mingw-src.tar.gz

This will create a number of new files, included several additional
tarballs and patches.

	unpack the upstream source tarball bzip2-$VER.tar.gz
	unpack the extra 'cygming-autotools-buildfiles.tar.gz' tarball
	cd bzip2-$VER
	autoconf
	mkdir ../build
	cd ../build
	../bzip2-$VER/configure [various options]
	make

However, the automated procedure, which can be used to exactly reproduce
the official mingw package, is:

	mgwport bzip2-${VER}-${REL}.mgwport all

which performs all of the above steps, as well as applying various additional
patches (from Debian and elsewhere), installing into a local staging area,
and generating the mingw-get compatible installation packages.  See
MINGW-PATCHES/bzip2.README for more information.
