Windows 95 & Windows NT users: 1. There's a pre-built executable, bzip2.exe, which should work. You don't need to compile anything. You can run the `test.bat' batch file to check the executable is working ok, if you want. 2. The control-C signal catcher seems pretty dodgy under Windows, at least for the executable supplied. When it catches a control-C, bzip2 tries to delete its output file, so you don't get left with a half- baked file. But this sometimes seems to fail under Windows. Caveat Emptor! I think I am doing something not-quite-right in the signal catching. Windows-&-C gurus got any suggestions? Control-C handling all seems to work fine under Unix. 7 Aug 97
