It's difficult for me to support compilation on all these platforms.
My approach is to collect binaries for these platforms, and put them
on the master web page (http://sources.redhat.com/bzip2). Look there.
However (FWIW), bzip2-1.0.X is very standard ANSI C and should compile
on the master web site (http://www.bzip.org). Look there. However
(FWIW), bzip2-1.0.X is very standard ANSI C and should compile
unmodified with MS Visual C. If you have difficulties building, you
might want to read README.COMPILATION.PROBLEMS.
At least using MS Visual C++ 6, you can build from the unmodified
sources by issuing, in a command shell:
nmake -f makefile.msc
(you may need to first run the MSVC-provided script VCVARS32.BAT
so as to set up paths to the MSVC tools correctly).

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.

to include the define -D_FILE_OFFSET_BITS=64 in the Makefile. This

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.

AIX: I have reports that for large file support, you need to specify
-D_LARGE_FILES rather than -D_FILE_OFFSET_BITS=64. I have not tested
this myself.

Y2K status of bzip2 and libbzip2, versions 0.1, 0.9.0 and 0.9.5
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Informally speaking:
bzip2 is a compression program built on top of libbzip2,
a library which does the real work of compression and
decompression. As far as I am aware, libbzip2 does not have
any date-related code at all.
bzip2 itself copies dates from source to destination files
when compressing or decompressing, using the 'stat' and 'utime'
UNIX system calls. It doesn't examine, manipulate or store the
dates in any way. So as far as I can see, there shouldn't be any
problem with bzip2 providing 'stat' and 'utime' work correctly
on your system.
On non-unix platforms (those for which BZ_UNIX in bzip2.c is
not set to 1), bzip2 doesn't even do the date copying.
Overall, informally speaking, I don't think bzip2 or libbzip2
have a Y2K problem.
Formally speaking:
I am not prepared to offer you any assurance whatsoever
regarding Y2K issues in my software. You alone assume the
entire risk of using the software. The disclaimer of liability
in the LICENSE file in the bzip2 source distribution continues
to apply on this issue as with every other issue pertaining

WARNING:
This program and library (attempts to) compress data by
performing several non-trivial transformations on it.
Unless you are 100% familiar with *all* the algorithms
contained herein, and with the consequences of modifying them,
you should NOT meddle with the compression or decompression
machinery. Incorrect changes can and very likely *will*
lead to disasterous loss of data.
DISCLAIMER:
I TAKE NO RESPONSIBILITY FOR ANY LOSS OF DATA ARISING FROM THE
USE OF THIS PROGRAM, HOWSOEVER CAUSED.
Every compression of a file implies an assumption that the
compressed file can be decompressed to reproduce the original.
Great efforts in design, coding and testing have been made to
ensure that this program works correctly. However, the
complexity of the algorithms, and, in particular, the presence
of various special cases in the code which occur with very low
but non-zero probability make it impossible to rule out the
possibility of bugs remaining in the program. DO NOT COMPRESS
ANY DATA WITH THIS PROGRAM AND/OR LIBRARY UNLESS YOU ARE PREPARED
TO ACCEPT THE POSSIBILITY, HOWEVER SMALL, THAT THE DATA WILL
NOT BE RECOVERABLE.
That is not to say this program is inherently unreliable.
Indeed, I very much hope the opposite is true. bzip2/libbzip2
has been carefully constructed and extensively tested.
PATENTS:
To the best of my knowledge, bzip2/libbzip2 does not use any
patented algorithms. However, I do not have the resources
available to carry out a full patent search. Therefore I cannot
give any guarantee of the above statement.
