+bzip2-1.0.3 should compile without problems on the vast majority of
+platforms.  Using the supplied Makefile, I've built and tested it
+myself for x86-linux and x86_64-linux.  With makefile.msc, Visual C++
+6.0 and nmake, you can build a native Win32 version too.  Large file
+support seems to work correctly on at least alpha-tru64unix and
+x86-cygwin32 (on Windows 2000).
+
+When I say "large file" I mean a file of size 2,147,483,648 (2^31)
+bytes or above.  Many older OSs can't handle files above this size,
+but many newer ones can.  Large files are pretty huge -- most files
+you'll encounter are not Large Files.
+
+Earlier versions of bzip2 (0.1, 0.9.0, 0.9.5) compiled on a wide
+variety of platforms without difficulty, and I hope this version will
+continue in that tradition.  However, in order to support large files,
+I've had to include the define -D_FILE_OFFSET_BITS=64 in the Makefile.
+This can cause problems.
+
+The technique of adding -D_FILE_OFFSET_BITS=64 to get large file
+support is, as far as I know, the Recommended Way to get correct large
+file support.  For more details, see the Large File Support
+Specification, published by the Large File Summit, at
+   http://ftp.sas.com/standards/large.file
+
+As a general comment, if you get compilation errors which you think
+are related to large file support, try removing the above define from
+the Makefile, ie, delete the line
+   BIGFILES=-D_FILE_OFFSET_BITS=64 
+from the Makefile, and do 'make clean ; make'.  This will give you a
+version of bzip2 without large file support, which, for most
+applications, is probably not a problem.  
+
+Alternatively, try some of the platform-specific hints listed below.
+
+You can use the spewG.c program to generate huge files to test bzip2's
+large file support, if you are feeling paranoid.  Be aware though that
+any compilation problems which affect bzip2 will also affect spewG.c,
+alas.
