Urgent need for an lz or xz utils build

I installed MinGW and MSYS on Windows XP but I needed an lzma compression
utility to install. I did build a beta version of xz utils and installed it
but it would be great if there was a GnuWin tool available. I know that xz
utils is not even a Gnu project. Please see what can be done.

Why not use xz from MinGW itself? See https://sourceforge.net/projects/mingw/
files/MinGW%20xz/

Otherwise use 7-Zip.

Okay, the details are that MSYS xz beta is available as a bzip2 archive. Also,
xz utils supplies its own source code as gzip archives. MinGW supplies its xz
utils binaries (and sources) as .lzma archives. The way I installed the MinGW
xz Utils package (which is admittedly not the easiest way) is to run configure
and make (install) within MSYS using xz utils' own source code. I guess it
would be alright to wait at least until xz utils is finally released into
production. Now I am configuring emacs to automatically handle the xz and lzma
(and txz and tlz) file extensions.

By the way, I installed an MSYS update for bash but got errors using its own
version of tar as well as the Gnuwin version. Finally I tried djgpp `djtarx\'
and it worked.

Thanks for the reply.
