+# For MS-Windows hosts, Julian's original build strategy, (and that
+# still adopted for building with MSVC), creates an unversioned DLL,
+# exporting functions using the __stdcall (WINAPI) calling convention.
+# Conversly, MinGW developers have chosen to sanitise the libbz2 ABI,
+# avoiding the use of the __stdcall calling convention, in favour of
+# the more GNU/Linux-alike __cdecl convention.
+#
+# To permit MinGW builds of libbz2.dll to co-exist, in the developer
+# universe, with MSVC builds, the MinGW Project has specified a scheme
+# for distribution of versioned DLLs, unambiguously named libbz2-N.dll,
+# where N is an ABI version number, nominally computed as:
+#
+#   SO_VER - SO_AGE	(ignoring SO_REV)
+#
+# Unfortunately, at an early stage in the evolution of the MinGW
+# versioned libbz2-N.dll, at a time when this version paradigm would
+# have yielded N = 1, a libbz2-1.dll was released, which employed the
+# __stdcall calling convention.  Thus, to avoid potential confusion
+# with this early release, and specific to the case of libbz2-N.dll,
+# the DLLVER for the __cdecl releases, as computed by the configure
+# script will lead the nominal value by one, becoming effectively:
+#
+#   1 + SO_VER - SO_AGE
+#
+# Note that for cygwin, a similar scheme (SO_VER - SO_AGE) is used,
+# but on that platform the extra +1 is not needed.

+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.
